it's not a good idea to compare ret pala defensive cd's with warriors defensive stance + second wind, when every1, even blizz, agrees that warriors are too good right now.
just a quick example. a warrior with 400k hp will heal for 12k each sec, wich means that you actually need 12k dps just to keep him at the same hp. and 35% hp of 400k is 140k. wich means that if he has no healer, and you got 13k dps it will take 140 seconds that's almost 3 minutes, to kill him when he has no healer on him... you can't compare that to any other class, because it's silly
so right now i can't see a reason for warrior + healer to lose to any1 (in 2v2 ofc, wich never will be balanced anyway)
i myself play dps monk, and find palas hard enough to kill with freedom, and getting out of roots, and protection, and DS etc. turn it around, my insta heal wich is on an 8 sec CD hits for about 40k, and my chi wave heals for about 15k x3 if i'm in range of my enemy. and is on a 12 sec CD if i remember correctly. I'm glad i will be given a way to break roots, like you have, but your healing will be way too good, if you are really going to heal for 50k with a flash heal with no CD...
wow, that got messy :P hope it makes some sense
