Bloodline Champions/YMMV

Excuse Plot: There's a background, but it's hardly clear what the game actually consists of aside from some references to "The Ancients".
Game Breaker: The balance of the game went many places in development, but the ultimate for the Psychopomp bloodline which doubles their main sources of damage and healing while reducing the duration of negative effects on them for 8 whole seconds is considered to be an issue. The "X-Strike" ability of Nomads' is considered to be pretty bad as well, as being hit by it guarantees you to be stunned and take a chunk of damage while it's being thrown, it can hit multiple targets as it involves two boomerangs being thrown and returning on the arcs where the other was. A staggering 40 damage can come out of it if hit right at the end of the curve of the two boomerangs...to say nothing of the damage that you'll also take from being stunned for the duration.
