remove pvp healing reduction because the state is good and people want blizzlike experience.
resilience will solve all issues (besides bugs)

(upper part where pvp players stop reading anyway)

Consider removing the healing reduction applied to pvp (arenas, battlegrounds) etc. to counteracts the state of too high damage and usually positive bugs that increase damage dealt. The obvious, better solution would be decreasing damage done by players, focused on targeted adjustments to certain abilities. thats complex and requires effort & time. it wont happen anyway at this stage any more, hence, at least make healers and hybrids more viable again and give them a chance to survive e.g. against rogues / warriors by not gimping their healing.

even worse, we have different reductions applied per battleground
