The FAQ says Uthgard does not support TOA, Cata, or DR, but what about the others? Shrouded Isles? Lab of the Minotaur? I really would like to make a Valewalker...

no, u did not understand. the shard is just without toa content, so everything below is supported, SI -Chars are all available.. mushrooms and necros not working yet. and many other pets missing too. but valewalkers are perfectly bugged so,get one fast. (atm vws absorb is the same as a plate-wearers,but hopefully that will get fixed soon..)

u can play with every addon, but u wont get anything else than the gfx of it.
