So, your rotation is CS>MS>Slam? And of course the obligatory cooldowns that every class ever has had. Sorry bro, that's not a complicated rotation. The Fury rotation in wrath was much more difficult to pull off. BT-WW-BT-Free, plus constant HS spam since your off hand attacks obeyed the soft hit cap while HS was queued. So your dps basically went up the faster you could push your buttons. And that wasn't even that complicated.
Really though, of all the classes and specs I've played over the years, (fury/arms/prot warrior in wrath/cata, fire/arcane/frost mage in wrath/cata, ret/prot pally in wrath/cata, marks/surv hunter in wrath, unholy/frost/blood DK in wrath/cata, demo warlock in wrath, mut/combat rogue in wrath) none of them have ever been particularly complicated. Though fury in wrath was probably the easiest to fuck up without realizing it. Pro tip, if you had white misses, you were doing it wrong.
I would say, instead of complaining about how complicated it is on the forums, go and practice your rotation to get better at it.
