What do you guys think is the cause of severe lack of Tank users?

Any death is recoverable, the game is designed around that way once you have the gear to comfortably clear the content. Note this part that I said: if we are talking about max item level characters then it's more lenient depending on the content you are doing.

This is definately not true. There are plenty of mechanics where you must have every single person do the mechanic correctly to not wipe. This also includes everyone alive as well especially in savage.

I have never argued against that. Of course, there are certain points where the boss will wipe you should one not be able to execute the mechanic correctly. But even then, the community has found different ways around that through smart use of LB3 or other shenanigans. The point is that you claimed that a tank death wouldn't matter, my counter-argument is that it doesn't matter for any role to die at any point since the game is made to be forgiving in terms of deaths during a boss fight as long as you are max-item level or slowly out gearing the encounter.

Should a DPS die during any point of the fight, unless he had a mechanic he was assigned to resolve, nothing will change and you will just have to make up for his dps as a party. Should he have a mechanic, a healer or tank will have to step in for him, and that's that.
Should a healer die, your only hope is that his co-healer has enough resources to sustain the healing until the other healer gets raised and has his mana back, this is excluding potential mechanics he will have to execute.

Should however a tank die, the first thing you will notice is the boss turning towards the other tank if he had some enmity, then the question is, does this tank potentially have debuffs from the last tank buster? If so, another tank dies. Then hopefully by that time you had a RDM so he could raise the tank that died, because as per usual, swiftcast is on CD and hard raise takes some time. But say for example that the tank dies and the other tank did not have a debuff post tank buster. What if a tank buster is coming? These days tank busters are either share, invul or swap. But, invul is usually on CD since you cheese the first few tank busters anyway in most encounters. Means he has to share or swap, he can't swap, so either a dps sacrifices himself and you hope that his sacrifice was enough to soak up enough of the dmg or you also die. No tanks alive at that point? Easy wipe.

So, as I said before, any death can be recovered.

But on topic again, tanks are just expected to do their job since their rotation is "easy" anyway and so is their enmity build-up, what people often forget is the support nature that they provide to the group with their tank CD's, group-wide CD's, and above all reprisal for AoE's. On top of that they have to study the encounter thoroughly to understand when to use a CD and when to keep a CD to mitigate the incoming damage spikes. This study is also important to place the boss in ideal spots to keep things consistent for the dps so they can have full uptime and positionals.

But hey, you can also wait a few weeks and then kill the boss because you outgear it anyway and then those small things don't really matter so any tank you find will do, but that also counts for dps and healers mind.
