this is actually really true. i was thinking about this yesterday while swapping between feral/mage and lock. classes that do extremely well in the game atm are classes that can mini burst frequently and force cds...imo. any class can force defensives and trinks with everything popped.. but if you can do so without using much you've just won the game.
EI - feral - tiger's fury[30sec] / trink [60sec] and lets say Nature's Vigil[2mins..maybe 3 i cant remember] - i think thats around 40% more physical dmg + X for trink [~5,200 agil but now like 3,000 or whatever it works out to mael trink]. thats enough to do serious hurt. and 1 min later with you healer's trink down you're going die if you cant peel him off you ( which is so fkn easy with a feral :| ) when he pops trink AGAIN and TF + berserk and Incarn no matter what his partner is doing. gg.
similar thoughts for mage.. ESP human mages.. no one's brought up how nasty the potential for double on use is going to be with humans, it's even more dangerous.
Conversely, my lock is really only threatening with dark soul up.. thats 2 mins.. 1 min trink makes less of an impact for me. i'll probably just run aff + double on use and max my uptime.
TL

R - i dont like that this change seems to favor classes already doing well. guess we'll see what happens.
