Well its seems this got missed form patch notes but according to some people in PTR drinking has been modified to abolish the use of 5sec drinking in arena.
Now drinking mana regen scales up in each tick regenerating very little or nearly nothing( 50 mana first tick, 100 second tick 200 tird tick..)to finish up regenerating its full mana at the longr ticks of the 30 secs drinking process.
Well this is a huge"nerf" for arena healing that dont know why has been miseed in patch notes.
According to game riot has been confirmed by blue although dont know if its right because gosey hasent mention it yet XD

druids? bye bye all other healers BUT druids..
it actually sounds like another huge advantage for them couse theyre basically the only healers who can drink such a long time, especially when nightelf stealthed

Oh shit, this is huge. Can't believe I have missed this, but thanks for bringing it to my attention. Will try to get some more details on it asap.

yeah its huge right now i think its a little bit bugged in ptr but when working as intended.. maybe we can see lots of changes in arena( mainly in 2vs2) after 2.4

its a plan to get wow balanced

as a rogue i can say: WOOHOO!

Its a major nerf for turtles!

Can anyone confirm this?

yea its confirmed by blue in wow forums, check for yourself to lazy to link ;)

its a very good thing, some games are rly ridiculus at the moment. i lost one game a few days ago becouse i run out of water before the enemy healer ( i "only" had three stacks aka 60 water.... )

well shaman water shield is op atm so the water drinking is gna be a big nerf to druids and also palas.
