I've always believed that asking the internet if you should play something is meaningless because every class bitches about how they're not king of the shitpile.
World needs more Goblin Warriors https://i.imgur.com/WKs8aJA.jpg
If you look at ranking summaries for H Fel Lord, you are right. Warrior is actually pretty low on the list, and only priests are lower.

(Then again, those results can be deceiving, e.g. fire mage being up there because there's so few parses).
Doesn't help that fury NEEDS the class trinket + EDH to be competitive on ST, and the HFC tier is hardly an upgrade over BRF until you start getting mythic pieces. I'm interested to see how big of a ST increase the 6.2.2 4pc buff will be.
Soloing Cataclysm content on a Warrior is/was doable at level 90, at level 100 it's more a question of how fast can you kill the bosses... Like killing Baleroc in under 5seconds on 25m HC, by collecting rings to get the haste buff on Alysrazor. If you go Prot you can solo MOP content and with the right gear even some early WOD raid bosses, soloing heroic 5man dungeons a piece of cake.

DO NOT even bother playing warrior now. For single target fury and arms are pretty bad, middle of pack, and next week 3 classes (shadow priest, monk, feral) are getting pretty big buff. These classes were under fury warrior on ST, after patch they will pull ahead. That means on single target only specs you can beat in dps (assuming you have about the same skill/ilvl/class knowledge) is ele and enhanc shammy and on occasion frost/unholy dks. Fights where u can bladestorm like Kormrok, if u have other warriors and/or demo locks, forget you will ever get good ranking. Sure your dps will be high cuz u will get few bladestorm hits off, but warlocks will beat you in dps no matter what. Arms for cleave is good, but nothing else. U will still get beat by locks, monks, priest mages, and sometimes hunters and rogues. Monks and priest already doing same cleave dps as arms (even higher), and after next weeks buff they will pubstomp you. Also ferals will pull ahead on 2-3 targets fight cuz of crazy rip and rake buff. Just forget warrior for this xpack and roll something that does dmg :P
