Warlock nerf wasn't as bad as I thought since energy burst, divine wrath and avenging light weren't impacted - but still too far.
I think a better way to fix the heroic problem is to only allow maximize/empower on SLAs UNTIL they reach character level 20. Getting 225 spellpower in heroics on those is too much. If they do this they can safely move spirit blast and eldritch burst up to 115 scaling with spellpower.
I think it was a mistake to nerf consume and stricken. Warlock single-target damage is below what the top melees put out significantly, although AOE is decent overall because of divine wrath and energy burst from ED.
I would only run warlock on a maxed out toon after the changes.
