I'm a little confused. What is your recommended rotation for engaging a group of trash mobs?
Let's assume we can charge in. I'm assuming you don't suggest rending first, before even a shield slam?
What I've been doing is:
Charge --> Shield Slam --> Rend --> Thunderclap --> Shockwave --> Revenge and other stuff
Is that right?
In randoms, I've been having trouble with that rotation because it seems the DPS have started in and AOEing before I get to my first AOE (third global cooldown, thunderclap). [which may be an adjustment all DPS are going to have to make...]
I don't think starting with SS is a bad idea. I prefer working this rotation so the DPS can focus on the first kill target. Opening w/ SS instead of just rend on the first kill target allows you to have a bit higher lead on that first target. Specifically on the trash mobs and such, I too had the same issues.
Regardless of our rotation in heroics especially, DPS has to get out of the AOE mindset. It's sucking healer mana and just making things a bit tough for us to do our job.
