Incindiary bonds works on bosses now, but the damage is garbage on all enemies. The best I got out of it was 19, and that was on a mob weak against fire. Most mobs were reducing my fireball from 120ish to 100ish, and most were reducing my incindiary from 85ish to 9ish.
Jeez Anet, heard of a little thing call PLAYTESTING? 5 seconds with that spell will tell you something ain't right.
