Adding a tank class wouldn't solve it either. Tanks would drift to the new tank class...so would others at first just as something else to hit 50 with...but within a month or so the balance would return as the DPSers return to their DPS mains or healers to healer mains because there's a large volume of people who have at least 1 of every role leveled at this point (myself included) and will always lean towards their favorite role even if there were 50 tank classes. We also don't know if ROG/NIN is the only addition. The only job FF11 ever released solo was SMN and that was only as a teaser in lead up to Rise of the Zilart. SE is taking steps to combat the queues if you take a look at the new CT. The default Duty Finder loadout is 1 tank 3 healers 5 DPS. I'm not sure what you want them to do about the verbal abuse. I personally rarely get dickheads like that in my queues that berate my tanking/healing and I don't sweat the ones I do get because any online community...any online game...is going to have those people.
