not any tank can do the same job , and he needs a lot less healing compared to bernice for example for general maps. And instead of placing another healer , u can simply place a dps. ALso he doesn't costs insanely more then other heavies either to warrant placing another slighty weaker tank over him.


PS: talking about karma , she can even replace nadia for that matter as a duelist when you don't want to worry about healing. See how that works ? DIfference being that karma and gelius fill different rolls , while nadia and karma fill the same place.
