Obviously no-one likes to get stiffed by bad teammates, but actually I'd support random assignments as well. I think the tournament should be a team exercise -- what's the point of even having multi-clan teams if it just means all strong clans can join together to have an even greater advantage against the weaker ones? Leave that kind of epeen measuring to the single-clan tourneys, try for balanced teams here instead.
I agree with okin, also, multiclan battles can be easily arranged in private by clanleaders if they wish to do, so they can seek their favourite clans as mates.
But an huge 160/200 players battle, with all clans and clan members invited and put togheter in random squads, or trying to make them even, could be something new.
Not just a "the best of every clan put togheter" but every player that wish to have fun, even the casual ones.
I'm sure the pecores could host 200 players without too much troubles, probably even chadz can now that he upgraded his servers.
My clan isn't the biggest but with some preentive warning i could bring at least 20/25 players, maybe more.
If we manage to do so i'm quite sure we could fill a 200 peoples server. Every clan (i hope)will follow their battlefield commanders, so it would be much more organized and fun then the regular eu_Crpg1 slaughter, without need to have a tournament like system with restrictions and epeen measuring. Just for fun.
Also, we could make some cool videos with 200 players fighting in a somewhat organized way.
