Is wow power lvl story doomed to be that tragic?
Wow power lvl does love its fallen heroes, no doubt, but I'm not so sure wow power lvl done, not yet. As for the set bonuses, I expect the mechanics of these bonuses to stay the same but the values may well come in for further changes before they go live. And the wow power lvl mana conservationism doesn't stop there.
The critical strike chance of your Shadow Bolt, Incinerate, Soul Fire, and Corruption spells is increased by
wow power lvl. Each time your Immolate and Unstable Affliction spells deal periodic damage, you have a 15% chance to gain 10% damage done by you and your pet for 10 seconds.
The 2 piece bonus is a straight buff to the main direct damage spells of each build. Corruption is also in there, which won't affect most specs, but will be significant for affliction,
wow power lvl needs this extra bonus as it, obviously, gets more of it's damage from DoTs. The spells affected by this buff make up about wow power lvl of the damage done by each spec and most of that damage comes from crits. My napkin maths says this bonus should shake out to roughly wow power lvl boost.
