I found I used to have similar issues when doing dailies. Since i got some badge upgrades and some gear from Kara, I find questing in prot gear a breeze...at least against melee mobs.
When doing most dailies in IQL for SSO rep, most of the quests where you need to kill things are against melee...I have barely any downtime because they just can't do all that much damage.
Even against casters it's ok, I put the shield on and bash away to stop casting.
