I look at your logs and it is here, yes BoH can be strong on some encounters, but Chogal 2,6% damage, thats realy soo strong, and Maloriak have similar numbers Magmaw with head exploit it is 10,9% damage, and head take 100% damage taken bonus. On every fight where is more adds you take Affli, because what? Because Soul Swap is stronger.
What I say before, on 70% of fights you have not chance do something like 15% damage bonus from this spell, and have no chance use 5 minute duration. Everyone say "oh good, 15% damage for 5 minutes with one GCD?! OP" yes, sure, give us every fight when we can use this and it maybe will be OP...
