While I'm a huge proponent of world PvP and think it should be as unforgiving as possible (even wanting flying mounts gone from the game) I do think faction imbalance is a big problem. Not just with the TI, but in general. It's irritating that so many players seem to have a hive mind and want to pool up on a server that's imbalanced in their favor, cause WoW would be much better off if they were even. I'll never forget the world PvP on the IoQ back in the day. My server was an almost dead even split at the time, and it was the most fun I've ever had in game. Now that server's hugely in favor of my faction (and dead, to boot) so I don't have many targets.
