A bug? or perhaps an "unintended" result.

Currently Resurrect Creature in the Taming Tree can be used in a way that probably was not intended.
If you have a dead friend that "refuses" to "accept" the res, you can attempt the res over and over and over.
Each time you try - you gain in that skill - as well as all of the innates in the tree.

Can't imagine that's intended, but perhaps it is?
Perhaps in the future you won't let us use Res Creature to res an avatar... ??
If that is the case, then this bug can be closed.
