I whole-heartedly agree with the need for a new Codex. I am first and foremost a CSM player, that dabbles with other 'dexs. However, I don't want legion specific...or Gods forbid, more of those stupid bloody Daemonkin codexes. I play a non-legion, traitor marine faction that is not soley dedicated to anyone god. I could easily do it, but it's just not fun and I can't make up fluffy stories on why my Chaos Lord seems to waffle back and forth on the Marks.
That said...I wanna see WAYYYY more troops and stuff on the table, but can't if I wanna remain competitive.
