Yes classes definitely need more definition as of now I feel like all the DD classes play the same way sometimes even use the exact same gear (arc and pug) (mrd and lnc). My gf plays both the conj and thm classes and even then thm is better of using conj spells with the exception of shadow sear. Point is we need more class specific skills like the lnc surges. Even the current r50 skills are not much to speak of.
