Well according to the Eorzea census role distribution form 31-60 is 38% healer + tank and 62% DPS which is actually pretty darn close to the distribution in a party make up if you factor in the 24 man raids as well. I'd also be willing to bet that the number of tanks has grown since the release of heavensward. So yes, while the data clearly states that DPS is a more popular role, I don't think it's as far off as people realize.
Additionally, from a business standpoint. If all players are paying the same amount of money into a pot then all players should in essence be given the same service. This includes all things in the game. Isn't it SE's contractual commitment, as a service organization in this instance, then to make the experience as similarly enjoyable for all parties? I've never met someone that didn't get excited by a instant queue. I understand that that is the "status quo" in the MMO world. I don't buy though that any company or person should settle for that because its the "status quo".
Maybe that makes me an idealist, but the world needs those too. This board is just filled with pessimism.
It did make me giggle though as I pictured my 1000k DPS in my head.
