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

DPS is much more lenient and the problem lies there, people will at most scoff if a litany or trick attack is out of sync. The dps role is very forgiving in the community and that's where the problem lies as to "why there is a shortage of tanks" and an equal if not more shortage of healers.

Lol, no. Right now Tanks don't die outside of stupidity or healers screwing up. Tanks almost never result in party wide wipes anymore, healers and I would argue DPS have far more responsibility than a tank. Tanks have lost almost all their responsibilities this expansion besides "live" which isn't a responsibility that is specific to them... that's for every player.
