Im a 2k warrior atm and I'm having quite a bit of trouble with my sustained damage. Sometimes its rather good, and other times it just sucks, but I don't seem to be doing anything too differently.
If im sticking on a target...
Colossus > Overpower (Spam procs) > Mortal Strike > Overpower > Slam > Heroic Strike (High Rage)
Of course if I'm planning to do a swap I save colossus smash and get some rage ect, and make sure to use high rage/stacked heroic strikes is ontop of another ability. But It just seems like other warriors in the same gear are able to put out much better sustained damage.
If anyone wants to ask questions about what I'm doing, I'll answer as best I can, or if someone can see somethign wrong in even how i've explained this I would love to be corrected and figure out what I'm doing incorrectly here.
