It would be very interesting with such a cap level.
However for myself, i would have liked to have seen a 25 or 30 player alliance cap on Kappa.
Had that been the case, we would not have merged with VRoD and i would have put my old alliance Skullduggery up against any other alliance on kappa and bet on them to win.
.
In the entire time we where together we only had two people leave, we like FC and RS, RSII etc, where a family, brothers and sisters in arms who fought for each other and helped each other grow, learn, prosper and survive.
Sadly qualities that are seemingly lacking in many an alliance these days, one of the major failings of overly large alliances it would seem.
ro: Not all fail at this, but most do, it is why i think Kappa is dying so rapidly, new players have to survive long enough to get involved and bring new blood to the battle ground, if they can not find or are not allowed to survive long enough in an alliance to learn, they will leave the world, sooner or later.
