The buff on ST is not confirmed, which probably means a nerf on akh morn/deathflare if they want consider buffing ST dmg to compensate

edit: We should not excludea 80 potency buff to F4, it's something they haven't done often but they did buff R3 from 120 to 200 with 3.2 so it's not something to exclude (albeit I'm not counting on it)
