You’re entirely correct in some ways, but I’m not sure about others.
it reduces the individual healer’s impact on the game. I get it, from the overall RBG perspective, it’s a net 0. Both sides do less healing, therefore what’s it matter?
It matters because better healers are hurt worse.
Your logic is: If healing is lower, healers will CC more because those globals are worth more now. Which may be true.
Another logic is: IF healing is lower, healers must focus MORE globals on keeping people topped up, as it’ll be harder to recover from major burst. Which is another valid way of looking at it.
Your entire point of “HPS rotations in Blitz is bad” may end up being more of a problem, not less. The better your healing, the more time you can confidently spend CC’ing, positioning and DPS’ing, because you HAVE TIME FOR IT. This reduces that time, not increases it.
There’s also the EXTREMELY valid point that this isn’t equal. That a healer that focuses on throughput, like a druid, may struggle even more than a healer that focuses on mitigation, like an hpal or disc priests.
And obviously this is a much bigger nerf to any DPS that heals itself, like a Fury Warrior or Aff lock. They’re gonna feel squishier.
Or maybe not. Maybe it won’t matter at all. I could easily be wrong about this, but my gut feeling is that healers are going to spend more time healing for the same result, be less able to do more nuanced plays and be more stressed about it. Maybe that’s a good thing!
But let’s not pretend it’s all obviously going to be better now.
