I think all classes require an equal ammount of skill to play them to their maximum potential.
Tanking is not harder than dpsing or healing, nor does it involve just standing there and can be quite challenging. In the end the difference is that if u make a simple mistake ( which could be forgetting to pop a CD in later ex fights) u can insta die, which usually results In an insta wipe
Try to remember all the primal fights and coils , how many times do Dps die per fight, quite a bit but they get raised and the fight goes on, however u simply can\\'t die which also depends on the skill of the healer.
So in short people throw abuse on tanks and so forth only because their mistakes are more obvious to see for everyone.
Dps and healers can be making mistakes all the time in a fight but u wouldn\\'t notice them
In the end I think it is fair that u got to do ex primals and coil for the mount , not everything in this game should be
