I've talked about Holy Paladins and Eternal Flame Blanketing before. It's the practice of putting 1-point EFs on many members of the raid, and relying on the fact that EF extends our mastery shield to absorb a fair bit of damage. At the time I didn't think it would be viable in raids, but it turns out that it is very viable. The majority of max healing parses for Holy Paladins feature this trick.
This isn't the way Holy Paladins were meant to be played. It's more like a Druid playstyle. Instead of being optional, Holy paladins are in danger of having this playstyle be mandatory. So Blizzard is taking aim at this practice. The last PTR version featured several major nerfs:
- Initial heal of EF decreased by 30%
- The HoT part of EF no longer gives mastery shields
- Make Word of Glory and Eternal flame cost exactly 3 Holy Power.
