Shifters are really not in a good spot at all.
Really, for a shifter build to be viable, the server has to be high magic, where it would also be acceptable to just hang out as a weird creature. You also -need- monk levels and to go hard in the paint with your wisdom score because mechanically, it's really just your wisdom that copies over that matters, and monks get their wisdom added to their AC, and also a movement speed increase. +5 Gear doesn't hurt either.
Shifter -can- be powerful, but not here on a level 20 max server, and they really only become powerful once you start getting feats to take Epic shapes like dragon shape and undead shape.
I don't think Shifter is a good fit at all for this server, it's severely underpowered, and extremely disruptive as none of their forms make IC sense for Barovia.
