DoTs are a solid place to buff if you can't get to mechanics, as it buffs AoE (slightly), ST and gives you more DPS in the case of a death (since DoTs aren't affected by our current AF/DWT penalty). If they changed too much, our rotation would be all over the place between patches, like MCHs are (and if you don't play one, trust me it is PRETTY ANNOYING). It's as close to a passive damage increase as it gets with the current SMN.

It's just not exciting nor the mechanical changes needed to fix the class, which we knew weren't getting fixed until 4.1.
