They seem to be trying to make fights take much longer.
Whats been a big complaint with WoW's PVP as of late imo? Health too high, burst too high. Outplaying someone without cooldowns may not matter because the health was so high, bursting with all of them rolling was the only way to take someone down.
Now the problem is theres a GCD on cooldowns that prevents you from rolling 3 of them and bursting, so players still have high healthpools but the burst that countered it is gone completely.
Time to kill is just way too high. If I'm better than someone, literally running circles around them while they hold the S key down, giving them more health just makes it take longer to kill them. It just wastes my time, and gives them more time for someone else to eventually show up and help.
I've played for almost a decade now. And in that time I've seen myself gradually losing the ability to beat players who are probably worse than me. Where I could once 1v3 people before by prioritizing targets, managing cooldowns, and outmaneuvering them, I now struggle to kill a single player because of the insane healthpools relative to my damage.
I guess I just feel that if someone has 30k health, I should hit harder than 3-4k. It shouldn't take 10 abilities to kill a player who sucks. Granted my sample size with the new stat squish is rather low. Most of my experience with the shite that is PvP right now came in Lesion.
