If they do keep the totems, it might help if they make status effects not work on them (with a few exceptions). Currently, trying to summon a totem on an area with two elements is a bad idea, as it will only be immune to the ground surface. Summoning a totem on a fire surface with poison in the air will make it instantly be poisoned, and sometimes die almost immediately, even if not attacked. And, since poison explodes, this can happen a lot.
The incarnate could definitely do with a visual rework, and I like the idea of having specialized infusions, or just more in general. Currently, it can only get a ranged attack or some melee skills. Perhaps the infusions could be made more powerful, diverse and possibly exclusive. (IDK if they are right now)
I also agree that Overcharge would be way more interesting if they blew up at the end.
