Just to get a consensus – what do you believe the top 5 DPS specs in arena are?
(preferably in order)
Arms
Fire Mage
WW
Ele
Shadow Priest
forgot ret my dude l.m.a.o.
might as well replace SP with ret
SP is stronger than ret overall
l m a o 10char
This is a good list
good except for SP. no way they are stronger than rets atm 
In no particular order: arms, fire mage, ww, boomy, ret imo
SP>ret from 9.0.5
Not sure about current
since it is a burst meta you should really add boomkin/ret/rogue
it is interesting because the meta changes significantly as you climb in rating, and setups you can count on at low ratings can often fall apart at high rating or be nowhere near as effective
Arms, fmage, balance, rets and we
Spriest, rogue and ele sham are only good in specific comps, but the first 5 can play with anything
Fire mage, Arms, WW, ELE, Ret
Fire mage
Frost dk
Arms War=WW
Enhance
Balance
Honorable Mentions aka A tier
Affli
Ret
Ele
arms
fire
ww
sp
ret
with fdk moonkin ele enh following
top 5 is tough as the 5th spot is really a bunch of specs now.
ret, fire
arms, ww
shadow, ele, boomi
past that?
frost dk, frost mage, arcane mage, feral, mm, enhance, destro, sub, affl
unholy, dh, sv, outlaw, assasin
demo, bm
Affliction is starting to excel. If warriors get nerfed even a tiny, affliction is going to be scary.
Fire
Arms
Ww
Sp
Ret/mookin to close to decide
both shaman dps specs as honorable mention?
nerf inc
frost dk, arms, windwalker, ret, fmage
Affliction is literally dog. No solo potential to kill.
Enhance is God tier with Warrior.
