Was kind of a bait, but well.
Havoc? One of the very best ST speccs in the game atm. Sure it is reliant to right legendaries to top parses, but what spec isn't?
Fury Warr are kind of shit overall from my experience. Weak aoe and weak ST. Obviously gonna get buffed.
Frost Mages are is really good, but because of 99% of mages running fire with corresponding legendaries, only a few mages got the correct gear setup for it.
Ele Shamans are just bad overall. Good aoe? lol not really if you compared to other top aoe speccs.
Fire mages have the strongest aoe in the game atm, and really good ST as well.
My point is; there is no class/specc that is niched into aoe and at the same time have awful ST. The other way around applies to some speccs (frost, feral, ret by some extent).
Oh and ret is not #1 dps specc in the game atm. Sure, we are VERY competetive with double bis legendary. But so are assass rogues, SP, Arms, Havoc.
Here is an example of logs for Guarm (M);
