Crit is definitely better than Haste, so that’s a step in the right direction. My bigger issue is that the set is still centered around Renew. It doesn’t add any meaningful gameplay or interesting interactions.
Now that the 2-piece gives Crit instead of Haste, the synergy between the 2-piece and 4-piece feels even weaker. They don’t really build on each other or create an interesting gameplay loop. If the 2-piece is going to grant Crit, I’d expect the 4-piece to actually interact with that Crit in some way. For example, crit heal triggers [some effect] or empower [some skill]. Instead, the two bonuses feel completely disconnected.
Honestly, I think the Holy Priest tier set needs a rework. Looking at the amount of redesigns and iteration other specs are getting, it’s clear Blizzard is willing to make substantial changes when something misses the mark. I just hope Holy gets the same level of attention.
