What even is the purpose of all those non melee/blm jobs?

rDPS was a mistake. Like, I appreciate it in the sense that it highlights the contribution from buffs in a way that people can easily see, but the hyper-focus on rDPS to the exclusion of the actual boss-killing DPS is maddening. rDPS is *not* the only thing that matters but you'll hear far too many people say - and truly believe - that it is.

The hyper focus on rDPS is no different than the hyper focus on pDPS was back in the day. It's just that it's more accurate than pDPS is, though it is a statistic people focus on a bit much compared to aDPS.
