So this bug seems to have many parts to it, it can either:
1. give you 8-10m health and normal damage
2. give you 8-10m health and insane damage
3. give you 1 health and insane damage
4. give you 1 health and normal damage
it is also persisting outside of battelgrounds and arena, i have just returned to dalaran and my health is double what it normally is. I wonder if this is affecting raiding as well?
