With the -15% one, buff to weapons and all, heavy DPS comps were already showing up, and now with a -30% one, i do not really know what will be the future of healing in PvP...
Druids take it a little harder since we need our HoT's ticking on outselfs to resist the change of target from enemy team in arena.
With the Shaman nerf, probably Paladins will be the most viable healer, since bubble still is immunity and will save they from pressure. And thats if they are even viable.
And the worst part... world pvp.
There we lack Pillars, and we need to use the scenario to our advantage.
With a 0% healing debuff, i could stand alive with only 1 dps attacking me, enough for me to run away to a city, or if they are poorly geared use HoTW to kill them.
Right now with -30% healing, i think world pvp will be a complete nightmare to healers.
We are already the worst role to play outside in the world, and with this we will be barely unplayable, i fear.
I fail to understand why they are doing this, i found pvp very fun. I like my arena matches to extend alittle, to take some time, to take skill, and not be a "use all CD's and blow that guy" kind of fight, where the first one to leave a pillar is dead.
I'd like to remember that with blood fear, it makes healers VERY squishy, since 1 blood fear out of pillar, plus target change to you, will probably be impossible to recover from, outside of paladin bubble. (And even then it will probably be hard for them, because paladins without bubble cd are very vulnerable...)
