I'm not too certain on the full ramifications of this. As I think through what this might do, I can see some semblance of its time convenience. But beyond that, this change might not change too much. I do not optimize my gameplay (yet) so maybe I am not the target player to take advantage of this hypothetical. I think it doesn't solve the baseline problem (the 2 minute meta) but in all fairness it doesn't sound like this idea is meant to fix it. I do think this idea is interesting and maybe could use some work. If the meta wasn't 2 minutes and instead unique to each job, maybe this idea would behave a bit differently. Though, I'm just some scrub so maybe I don't know.
