i guarantee you all, i can make these times see like easy as they always have
here is how it works
play your spec as normal, but use the new stuff like you did when using pots, trinkets, stuff like that
nothings changed really that much in the rotations
edit spot: im a survival hunter and engineer so here is how many abilities i have, and i dont ahve a problem
serpent sting, black arrow, cobra shot, dire beast, murder of crows, engineering gloves proc, explosive shot, arcane shot, kill shot, agility potion, racial rocket, long cd's rapid fire and readiness
not to mention snake trap misdirection
situational tranq shot
so now think of this,, during cata only difference between these spells we use is, just the new dire beast murder of crows atm
so 2 new abilities isnt that big of a deal to include in the rotation
