The appeal of DRK to new players is in how little they know of what people think of it, as well as how little they care about the meta. This is also what people brand new to the game look at when choosing their beginning class. Naturally, more often than not, they choose a DPS since there is only 2 Tanks and 1 Healer available at first to choose from, but of course those that pick Arcanist can opt for Scholar as they see fit. Opinions change over the course of gameplay after they get to know a job enough, but initially appeal is in job aesthetics, not performance. And personally, I don't have the metahate boner so many others do toward DRK just because it's outdone by PLD and WAR. Far as I'm concerned, it does fine, and DRK is my go-to for tanking.
It is true not everyone turns away from Healer and Tank despite the grief they typically get, and said grief is also situational depending on who you get in PUGs, and yes DPS get their share. It is an ongoing finger-pointing war after all. However, when it comes to easy content people tend to find DPS more laid back as all they have to do is deal damage and let the Tank and Healer worry about covering them. Sure DPS tend to employ their supports and do their rotations and AoEs but not everyone actually bothers when content is easy. Now I can't speak for the Savage community as I, being a casual gamer, don't live in difficult content so I speak from what I do know, as well as what I have heard. Sure it's not entirely factual, but then again what job/role you choose is entirely based on opinion anyway.
You're right in saying that I can't speak for everyone, but when you look around in your server community and on the forums you get a general gist of how many feel. Sure that only accounts for a fraction of the entire playerbase but we can't exactly say those unaccounted for don't feel this way. I'm not trying to tell anyone this is how people feel, I'm just giving reasons DPS jobs tend to be more used than Tanks and Healers and thus result in high queue times. Am I right? Am I wrong? I can't say for sure, I can only speculate. Either way, the fact remains that tons of people play DPS. Even the typical 1/1/2 role ratio is not entirely close to that ratio as there are more DPS players, hence the longer queues.
TL;DR version: My beliefs on the reason DPS queues are so long are irrelevant until proven factual as they are speculation and nothing more based on what I see and hear from others. The relevant thing here is so many people play DPS over Tank and Healer that it causes long DPS queue times as a result, regardless of the reason why. Until Tanks and Healers see a surge in usage, this will always be the case. Call my reasoning what you will but it doesn't change the fact DPS usage far outweighs the DPS/Healer/Tank ratio, which is why DPS queue faster into Raids.
P.S. I do not like Linkin Park nor am I an edgelord and I prefer to play DRK over PLD and WAR. Such stereotyping is just plain wrong...
I think you take the reasoning behind just waiting for the queue for granted. The more you preoccupy yourself, the more that queue wants to pop on you when you can't get to it in time to proceed. Of course the opposite can be said in that queue times figuratively take longer when you do just wait, but that's just how it is lol
Also I don't do nothing per se, I will occupy myself by wandering around, reading a chat conversation/engaging in one, checking on some things, etc.
