Dungeon leveling IS the fastest way to level a job, of this "luxury" Tanks and Healers partake, but DPS cannot reliably. The Queue times are long, often taking me 10-15+ minutes to play in a 25/30 minute dungeon.
Add to that the fact a lot of the game's content is Duty specific (Trials Raids Dailies Dungeons) making it feel you are actively discouraged from trying DPS jobs.
I understand that it's not to the creator's discretion to make DPS have fast queues, which is a by product of Tank and Healer gameplay and why they're not as popular, but some measures have to be taken so DPS doesn't take suuuuch an long time to even get running,
i myself play since December, and in my course of 1k hours + only my reaper is high level dps because he starts at 70. I started the game as a Monk, got to 60 and gave up, transitioning to Tank,
over a half of the game's playable styles depends on the player's patience. The game's boom in popularity and over a half of Jobs being DPS will only make the problem bigger.
Please, perhaps rise the XP DPS gets for Dungeons or other activities, "just try Bozja or other mode" isn't a good argument, you're secluding a portion of the player base because they want to play in a relatively good time (Try Queueing up for a daily duty as Tank or Healer to see my point. It's super fast) and again, Bozja isn't as good to level as Dungeons.
Also Bozja requires you to at least be level 71+ DPS, so you have to get there...
Changing healer's tool kit would also be a really really good decision to boost Healer player rates, thus reduce DPS Queue lenght. 2 DPS Buttons ( Sage has technicaly 3) for a healer isn't fun, it's boring, this isn't just accesability, this is stripping down a role to it's base needs just to get by, i do not expect Healer to have as wild of rotations as DPS, nor anyone wants that. But 2 buttons that actively deal damage just isn't enough. (spamming Key 1 and then every half a minute key 2)
I always wanted to play DPS jobs (which is the majority of the Jobs) but in the current state i could play way more of Tank which is a good middle ground from DPS, and not waste my time (DPS Queue) while not being bored (by Healer damage gameplay and DPS Queue)
Why would i play DPS if there are so many hurdles to get to fun gameplay.
(I have a lot of hours on Healer, i enjoy the healing but the ease and mindnumbness of pressing 2 buttons to deal damage throws me off.)
