Archer barbarian+crusader? Hey, you can even try out a battlefield control archer (use Arrow Mind to gain a threatened area, or the stance from the Falling Star path...see handy haversack...and Stand Still: it's not restricted to melee attacks). One of the twins then goes melee and pound the enemies into oblivion while the archer keeps them in one spot. Could be evil.
Also, SiFir, check out the homebrew forum. We are working on fixing up the system for Avatar, so hopefully it can be nice instead of what it is now by the time we start. Water is mostly done, it's just touch ups that need attention. Earth will soon follow, then fire/air, but those aren't important.
