What are you trying to say? That SE shoudn't bother trying to make the healer role fun/amazing, because 'DPS will always be more popular'? Additionally, there's a difference between 'Healer (24% pickrate) is not as popular as DPS (54%)', versus 'Healer (12% pickrate) is not as popular as DPS (62%)'. In both examples, the statement 'Healer is not as popular' is true, but in the former, the number is much closer to the right balance, because we need 2 DPS in a party and only 1 Healer. DPS is MEANT to be more popular, the game's designed that way. If Healer were as popular as DPS, or more, then we'd have dungeon queues grind to a halt because there's not enough DPS in the queue to serve all the Tanks and Healers.
I'm fully aware that HW is gone. I don't actually want HW though, I'd prefer something more like SB. Far more accessible for casual players, far less punishing, still gave us depth to chase. The 'best combined healer run' of O12S still had some GCDs in it, because optimizing a fight to be clearable with 'zero healing GCDs used' was something to aspire to but never truly achieve, now it's commonplace. But since you imply I didn't read:
I did already quantify the numbers as 'maybe they have merit, maybe they don't'. I dunno if they're real or not. Only way to know for sure either way is if SE were to give us the data themselves. Until then, estimations done by third party sources such as FFXIV Census, or Lucky Bancho, are all we can go on. On which note...
'Lucky Banjo' (lol) is a third party as much as FFXIVCensus, and if one can be used as a citation (as you are here), then the other (the FFXIVCensus numbers I quoted previously) can be too
Lastly, I've seen some Vanilla WOW census data (which is a lot easier to get because they have addons for such things) from around a month ago, saying that for a lot of PVE servers, Paladin (which the majority of players will play as a healer) and Priest (which is played as a healer) have a higher playrate at max level than Rogue (a DPS) and Warlock (a DPS). On the Horde side where they have Shamans instead of Paladins (but are also played mainly as healers), they too are incredibly popular, and have not only higher pickrate than Rogue and Warlock, they're equal pickrate with Hunter, and are a very small gap behind the pickrate for Mages, of all things. But maybe Vanilla WOW doesn't count, because it's too old, or because back then there was more reason to bring a specific class (eg Rogues are needed for the Suppresion Room in BWL, or Hunters are needed for Tranquilizing Shot despite having lower damage than some other classes), so it's not apples to apples. But I'd also posit that maybe Vanilla WOW is a good example actually, precisely because it's been out for over 20 years, people know that the DPS specs for Shaman are not so great (doing like, 25-35% of the damage of an equally geared DPS Warrior), and so the vast majority of people who decide to play a Shaman go in knowing that they'll be healing at endgame
I'd also estimate that more players play certain Healers here, than certain DPS (eg I expect there's more WHMs than BLMs). The issue is that we have 4 Healers, and 13 DPS. But, if SE releases a new healer (to eventually try to have 7/14 and have the Healer/DPS ratio of 1:2 that the DF format asks for), the addition of Healer jobs won't take from DPS numbers enough, instead it'll be mainly already established Healer players, swapping within the role. Maybe if SE were to add a proper 'DPS focused Healer', that is, one with an actual rotation, they'd actually capture some of the players who usually go for a DPS. Giving the playerbase four Healers (or five in the future maybe), that all have the core damage rotation of 'refresh your DOT twice per minute, then press <filler spell> to fill', doesn't attract as many players to the role as could be attracted by having the Healers have different gameplay designs.
