Simple enough, most warlock abilities are specifically screwed by this new system. Key point is Song of flame is affected by the class, grenade and melee regen (0-100 stats) so If I don't build into those it charges them slower during use and still doesn't benefit from the bonus damage of 101 to 200 of those respective stats Not to mention the grenade stat not working with Stasis turrets, Healing nades / Turret, Ionic sentry or Arc soul. Nor anything for the class based focus abilities (Arc Souls, Threadlings, Child of the old gods or Hellion So why was non of their kit even considered?
