No. You don't need vanity mounts to play the game, but you need essences, so that's a false equivalency. About the third one you've used so far during this annoying exchange. False equivalencies are a waste of everyone's time. I think talking with a loaf of bread would be more interesting than talking with you.
Negative. You must either be new or didn't try doing tower until severely outgearing the challenge.
MMOC did an unofficial break down of completion and the bottom was tanks (sans guardian) and outlaw rogues all below Guardian and then the rest of the specs.

Outlaw cleave was not a thing, you still needed to focus down specific imps.
The sin challenge was a joke. The sub one almost equally so as it only required positioning.
Agatha was a joke to most other classes. Namely feral (lol) and ele (which with proper legendaries could just stand and burn.
All I'm saying is that of all DPS specs, outlaw was right there struggling with (if not more than) most tanks/healers. You'd be a fool to think otherwise.
Outlaw's participation rate on that chart was low because outlaw was the worst raiding/M+ spec for rogues so the participation % was low.
People played outlaw to do the challenge and then never again 9/10 times.
Of the specs that did agatha (and weren't low participation specs like feral), only outlaw and ele have lowish completion rates. Fury warriors which have just as much, if not less cleave than outlaw did at the time, has a higher completion rate because it was played more. Hell, all the chart does is show which specs were popular at the time the armory scan was done. Outlaw then isn't outlaw now.
Also, I did my rogue mid ToS in LFR gear, all you had to do was gouge one of the 2 imps that spawned from behind, kill them in order and go back to agatha. You had more than enough cleave to kill the imps that spawned in groups. How else do you think fury/unholy/feral did it?
