You can just hit your allies with magical poison dart for direct heal+aoe on top of the afore mentioned combo + it barely counts as a punch to roleplay because in both D:OS 1 & 2, npc's don't react to you having that talent.
Also fights vs poison are a joke when you have the zombie talent.
Well, what about that talent visibly changes you? Do you walk -oddly? Moan about wanting to eat brains? Smell of corpse-rot? The talent certainly doesn't say you do, so there's nothing for NPCs to react to.
And yes, it makes SOME fights easier, but it's obviously going to make a lot of other stuff harder. Such as healing - those poison darts heal way less than the restoration spell, for example.
But it still affects roleplay. You have to worry about healing surfaces such as bless or especially holyfire, you have to worry about, if you want to heal in town, leaving behind poison that will injure others and cause hostilities. Yadda yadda.
