- Critical Mass - nerf reverted. It's back to 30%.
- Pyroblast - direct damage reduced 10%.
Regarding reasoning, they listened to those of us saying the CM nerf punishes those without very high end gear, and it looks like they might actually attempt to fix this long term, instead of simply forcing fire mages to constantly ride the "get good gear / get nerfed" merry-go-round:
The Fire changes were because we needed to nerf Fire to keep other mage specs competitive in PvE in 5.2, but we agree that nerfing Critical Mass unfairly targets less well geared players, and that the spec is just less fun if it crits too rarely. (Long term, we might investigate some of the non-linear percent scaling suggestions players have made.)
