You’re playing in a DPS spec, right? Because in my tank spec 2 is easy, 3 is doable but leaves me below my max health if I don’t use my defensive cooldowns, and I have found out from bitter experience that it is possible to take on about 8 at-level mobs (not casters, though) without using Army of the Dead and come out alive - there’s a quest in Uldum where you’re supposed to use a quest item to distract the packs of monsters so you can click on the clicky thing, but I didn’t read it carefully enough and just waded in, expecting them to be below-normal-strength mobs.
