No one would even care that you cant DIRECTLY peel rogue for 3 seconds (although obviously almost any class can peel indirectly).
Lets not forget that subterfuge is great survivability talent which isnt something rogues can spare and it feels very rogueish and not some passive mitigation warrior-like sht.
As for c&d at the current state of the game it doesnt even feel that OP. I mean its possibly too strong on openers but i wouldnt like to drop it while dancing because, well, dance is the only thing that is scary about rogues atm and its not too hard to peel / use sht during those 6 seconds so cnd helping in that department.
I mean, obviously it feels hard because rogues do stupid amount of damage even through defensive cds, but thats not the fault of cnd or subterfuge. Its like... if rogue is lucky he can literally double evis through cds for like 80% of your hp and in this topic people go "ye, prolly subterfuge and cnd are stupid and too op". Ye, sure, its all subterfuge's fault ><
