Ok, here is top-12. Don't shoot me straight away, just trying to stay on topic.
1 Eviction Notice 11343625 SWIM
They use the proven concept of playing grepolis. Everything you need to win the world is here: strategy, players, leaders, experience, numbers, pacts, participation, wars. The main favorite apparently. Rather innogames will dissolve grepolis's web-designer team, than EN will lose a grip in Abdera. They have taken 054 under control and made 044 vacationland cemetary for ex-Average Joes and Just the Tip players.
The next move will be interesting to see. Who will be the next in ocean 44, maybe Dragon Hunters or they will go to ocean 45 to finish JTT? Or maybe they will turn to the east and face QoQ? Anyway hundreds of cities will be taken by this team.
2 Quality over Quantity 11115861 SWIM
I would name their strategy as a "new wave of grepolis". It is based on clustering in one ocean, allegedly simulating bp by killing their own troops, converting it to city slots, and building up cities from scratch. It is all sharpened for WW era. Additionally they prefer to stay a tight group of players and those players are experienced. So we had better consider this alliance as a contender, maybe closer to WW stage they will revise their tactic and take in some players to get numbers for sending resources. But even today they are able to finish 1-2 WW at level 10.

4 Written In Blood 9443377 Merge
It is always hard to play in the core, you need to worry just about every side of your ocean and show reasonable diplo skills. From this situation they got the best they could. Despite JTT complaints, they made the right choice and secured north. I don't see them as WW builders, but they will do next: cut the extra weight and form one main alliance from big active players who will survive "hardcore in the core" and one sister with 10 city nice guys. Then they will merge to other alliance (supposedly northern alliance) closer to WW stage.
5 Nuns With Guns 7855322 Merge (with VI) or Sink
They own ocean 56, and their future depends on the next move. Alone they are not contenders and if they fall in war with their eastern neighbor, I predict they will lose. If they fall in war with their northern neighbor, I predict the same (unless they make a solid pact with QoQ, although QoQ seems to be not really interested in ocean 55). To conclude they will face two choices: Merge with other alliance or stay as a small-rim-alliance. In my opinion they will surrender to or merge with Vanilla Ice sooner or later, if they want to stay competitive. They just don't have another option. Well, there is a possibility for them to merge with Bloods, but Bloods already have 3 branches.
6 Just the Tip 6597703 Sink (split to LD and DH)
They're having hard times. Initially they had the same enviroments as EN, decent experienced players, solid team, core ocean. But from the first day they started to complain about EN and were so infatuated staring at EN's lawn, so totally forgot about their own. Then a beatiful garden became a dense forest, the forest where leaders hide in 5 days intentional ban from attacks. It's not a secret of pandora how that's happened. As I said, they had everything, but let's look closer at what their leaders have done and we might even write a book: "How not to lead in grepolis". They easily could have worked on their own alliance, collect dbp from northeast front - convert it to city slots - and expand step by step in their core ocean, fortify borders, but they chose several weird pacts with unorganized alliances like Average Joes, and concentrated on skype talking to form a coalition. Then they made even worse move - took in 044 players (put them to The Shaft mostly) and got hundreds of cities to defend from EN. There was no surpise they were losing dozen of cities, and guess what? They blamed inno event and manticore nukes. Don't get me wrong, I'm really sad to see JTT sinking, as I expected a good fight here, but their leaders acted and still acting like grepo-novices. They're losing a war to their inner demons.
7 Vanilla Ice 5272736 Swim (Merge with NWG)
This guys from Sinope (where they have shown wise leadership and terrific teamwork) and we can recognize their style here. They took ocean 66 under control and this world has just started for them, as their next move will determine their future. Basically they have two choices: battle for the east (vs QoQ) or battle for the south (vs Nuns With Guns). I bet the second option will take a place. So finally we will get the potential contender here. Definitely it's worth to watch after them.
8 Dragon Hunters 4814329 Swim
At the first glance it's a Rim allaince fighting another Rim alliance The Hammer to control the Rim lol. It's typical to such project to have the dozen of novices (noobs as they named in grepo community). They may attack with swords and defend with LS, but we shall not be mistaken and we can see a potential here. First of all, they get a benefit from all EN wars. Noobs can be taught and become reasonable players. We have to add ArjaaneZ factor here. He's smart, experienced and master in building a solid alliance from several small teams. But a lot has to be done: all those alliances Tuatha, Independent, Nameless and several others should be accusited. If they fight one-on-one against The Hammer, they will win this war and take under control wished areas. Tell you more, maybe they will take few JTT/Shaft guys on board (if they fell). The only danger for them is getting too close to EN, which they will avoid I feel.

10 The Hammer 4267374 SINK (or float as an extra small team)
Rim alliance. No surprises here: small group of players who want to play together, in process of time they take on board few novices, and here another The Hammer branded alliance and another battle for the rim. Basically The Hammer appears in every world, never seen them as a real contender though. (kinda like Harpoon). I think I'll never understand the motivation to play in such alliance.
11 Legion of Death 3956096 - SWIM (risky bet though)
Another small alliance with potential. They're definetly getting a benefit from JTT hysterics and Sir Henriksen is popular among JTT guys, so when JTT players realize that they have an option to change leaders and play under wise leadership (and if sir H. has time for leading properly), they will jump to LD and try to keep ocean 45 under control. I suppose LD will keep it classic and expand in ocean 45, then move step by step. But if they take ocean 44 players in, they will be doomed just as JTT, minus hysterical component I hope.
