I lol'd at "you can speed run just fine with any job".
Did you actually try it before saying that ?

A Rng for example does 1/4 damage of a Blm output on Chimera. Now say you take 5min on Chimera by stacking Blms, how long will it take if you stack Rngs instead of Blms ? 20min. Where is the speed run ?

Stack front-line DDs on the Coincutter, who can only make 1 or 2 ws before having to stop or move to avoid Swing, do you really think they can be any faster than a bunch of Blms and Rngs ? DDs best part of their combo is their last WS, how can they be fast if they can't do it ?

You'll answer that they just have to time it right. I'll say no, just no. There's no reason that some jobs have to suffer the need to time their combos right, and probably get hit or OS'd while two other jobs can just spam from a distance, while keeping the Whms safe with their already troublesome hate since they have to heal a tank that gets hit for 2~3k.

There is no way you can speed run "just fine" with any job.

And don't even get me started on Princess Myrmidon...
