DPS mentality in MMOs

[Adrestia]

1.) The developers of MMOs in general are caring less about tanks and healer then they do about DPS (development wise). Some even go as far as eliminating them altogether. (Tactical flashpoints for example).

This has less to do with player mindset of "gotta deeps!" and more with the fact that the holy trinity is quite long in the tooth. I personally do prefer tank/heal/dps along with an appropriate support component, but the fans have been calling for action-oriented MMOs for over a decade now. Not everyone, but enough people that a lot of games have tried it/are trying it.

2.) People tend to encourage dumb behavior in dungeons in favor of DPS. They want in and out of the instance as fast as possible and care very little about anything other then doing as much damage as possible.

There's a lot to unpack here. First, dumb behavior is dumb behavior, and that includes obsessively focusing on defense (https://www.youtube.com/watch?v=jBLsjnqcXsI), bombing heals every time someone reaches 99.82% HP, crafting using delineations and 999-step whistle garbage, AND doing dumb things in the name of DPS.

Second, a large part of why you see many people wanting in and out of dungeons as fast as possible is we never wanted to be there in the first place. "Dailies" have been thrust upon the MMO genre due to a great deal of psychological manipulation to make people log on every day and stay subbed for fear of missing out. The rewards are set high enough that we grudgingly trundle along through these dailies because it's efficient, but that doesn't mean it's fun. Especially if the only mantra is "play it incredibly safe" which, to those of us who have run the dungeon 3000x but also don't want to watch Netflix, is most challenging because of the risk of falling asleep in our chairs.

Third, and this does follow the second a bit, the reward structure only rewards fast clears. There are no extra tomestones for least damage taken, maximum HP restoration, or any metrics other than the binary "did you complete the dungeon?" And completing the dungeon happens through damage. Nothing dies because it's being tanked. Nothing dies because you're healing. It may be a depressing utilitarian way to look at it, but tanking and healing are the things that let you do damage more effectively (by virtue of not being dead).

None of that is to say that tanking and healing aren't important. They are effectively force multipliers. Having some of each vastly increases your damage and the jobs that tank and heal are heavily valued. But you can have "too much" tanking or healing. You can never (outside of certain bugs) have "too much" damage.
