First of all tanks and healers are always mentioned as "support roles" the definition of support is: assistance or a thing that bears the weight of something.
Damage dealers are never mentioned as "support" even tho there is a holy trinity tank, healer and damage dealer there is some underlying acceptance that damage dealer is the "normal" even tho tanks are needed and very rare, so is healers and for hard content they need eatchother, they are equally in demand, yet only 1 gets the "normal" status and the other two stand in the corner as "support".
What really gets to me is the fact that not only are tanks and healers in demand - especially tanks, but when you choose to go the "support route" you automatically say: I've just taken away the enjoyment of doing overland solo content and questing, I now do damage like a wet noodle and the only meaningfully existence I have is to be of use to spoiled glass-cannons in dungeons and trials and if I'm lucky I might get a damage dealer that do more than just lightattack
It goes beyond me how poorly and utterly horrid this game caters to tanks and healers and it's an imploding system since you get dps queuing as tanks, they end upp in dlc content and ruin it for the damage dealers that actually waited 20-60 min for their spot. Usually the group disbands because you all know it when you are in a PUG and you have to fill a tank spot, it can take a while and a few kicking fake ones that joins.
What I'm implying here is; I have so much understanding now for the lack of tanks and healers in this game, I played healers and tanks in other mmos and when you where a tank you felt like a king. Never had any issues with overland content and you felt needed.
I've tried every role in this game and as a damage dealer I've had the most fun since I also enjoy questing and there are so many damage dealers that can't put out the numbers that's why I started one because my first character was a templar healer back when eso released and after a while I just got tired of the low dps Pugs, started a sorcerer and carried a lot of players through vet dungeons, soloed every worldboss, got praised for my "high deeps". As a healer I've never felt whole, I felt dependant on others to enjoy the game, and soon no one needed healers anyway.
Don't get me started on tanking since the attributes need to be even more balanced = no dps at all, if you are not in a group you might aswell log into another character since killing a troll takes longer than killing a WB solo on a damage dealer
And the worst part is it costs gold to respec, a damage dealer never have to respec CP or change skills, you go from trial to solo and questing. A "support role" need to switch skills, gear and CP.
Of course the majority of players play damage dealers(or try to)
I play on console so there is no quick swapping gear or pre-saved settings. If that would exsist for "support roles" and be free or charge there would be a better balance - more tanks and healers.
I'm just so disappointed..
