Basically what this means is that bulwark gyro/guard! will only ever give 33% dmg reduction if you don't have protection. If you have protection, you only get about a 9% dmg reduction or so. A massive waste of a utility slot.
Dolyak stance is additive. This means 66% dmg reduction with just dolyak stance and prot. Becomes even more disgusting in WvW. Soulbeast is a well balanced class.
