That doesn't change the fact that I can both heal ,dps and no one dies so its not really an issue in raids/dungeons. I play pvp n the extra vit helps when a warrior pops up , gives me a safety cushion whilst I swifcast blizz 2 -> aura blast -> sprint -> ruin 2 to safety. If your healer assists in killing things whist still successfully healing, my most recent parser check was 659 dps over a fight and burst dps of 830 so hardly what you'd call bad from a role there to heal.
Please explain how spell speed actually works currently then as I seem to be severely misinformed, i got my info from the in game description when ya curser over spellspeed on character menu? Whilst DT is on cool down I can adlo shield full party in 12-13 seconds utilising stagger steps with current build. Can a full crit scholar give me your dps figures along with crit/det n any other relevant stat as a comparison?
