Which of the following are the high aDPS/nDPS jobs? Which job actually has the highest burst in practice?



That's the downside of reducing everything to a single number.

Buff synergy depends entirely on your burst, but not all 'selfish DPS' are burst-focused. VPR and BLM rely on consistency and uptime to do their damage. Of course, you could have predicted this entirely by usage rates in Savage speedruns. Shorter clear times favor burst. (I'll also say, I think Criterion Savage is looking to be especially hilarious, as triple PCT is already the standard for dungeon speedruns given how motifs reset instantly between encounters).

I'm not entirely sure what the 'advantage' of being a 'selfish' DPS is. It's certainly not utility. It's not necessarily even burst. It's not even buff alignment, and if anything you have to be extra aware about how the rest of your teammates are setting up their burst to get the maximum advantage out of your own, especially if you're in PF. Perhaps a better term is 'commensal DPS'?
