Had about 6-10 hours of playing without CW/RD (I mostly just used CW on every single toon and dropped the RD after I stopped doing WB's) - but I will say that for my average groups it is an extra 1-3 deaths per SC. I mean in general being on destro 75-85% of non 6 man (premade SC groups that order brings which are WL/WH or WL/SL) - so other than maybe using it for the IB outgoing HD or after a KD and WH/WL pop on you I didn't use it as much. However in the pug SC/normal RVR scene/non 6v6 SC I used it nearly on CD as we always run melee groups so you are going to have to eat some BB's, generally 2-3 as a melee player with NA ping being 100-150 for most.
Point being - it has just made the melee need to be a little more cautious in my recent groups as far as 100% being on top of never leaving your guard. I like to think I play with fairly good players and everyone makes mistakes but now you really just can't make as many. Rather than being able to hit that button every 5 minutes to save a death, you just have to eat the death. Sure you could do (name the 4-5 defensive things) if we were playing in a vacuum of perfect playstyles - but in reality CW saved a lot of people a death almost every time it was used.
Other than M2 for DoK becoming 100% mandatory as in use M1 very very very sparingly - and also using group cleanse on CD becoming more of a "on the milsecond" rather than just "every time it is up" - I haven't noticed much difference. But I will say I have actually caught a few ranged trying to get away since they can't pop RD. But all in all I think it was a good step in the right direction, just please don't make quick escapes go away
