If tank builds weren't so expensive, fussy and precise in terms of specs in this game, I'm sure more people would tank. At the end of the day, the actual role of tanking isn't that hard for most content. It's just...well, here's an example: you're a new player. You got your starter DPS build. You're learning it. You got 1 or 2 weapon skill lines levelled up and you know how to do a decent rotation. Then you want to getting into tanking. But oh hold on there! Do you have the right sets? Do you have other sets to be flexible as an offtank? Do you have all taunts unlocked? Do you have warhorn and barrier? Do you have sword and board levelled up? Can you also backbar a destro? How much health do you have? How's your mag and stam recovery? Do you know what you need if you don't have good resource management? Do you know what glyphs, traits and mundus you should use? Do you know about overtaunting? Do you which bosses can't be taunted and know what to do there? Do you have this and that addon? And so on...it's too much for most players. And honestly part of that isn't even the game design--it's what other players expect from tanks now at this point in the game's evolution.
Maybe lower your expectations for what is a tank. This community could start with not calling every tank people think is subpar a "fake tank."
I am not sure why people would be against encouraging others to play as a tank by giving an incentive like other MMO's do to help fix the que times. The tanking incentive could just be a once a day reward for choosing to tank using the LFG tool as well. It's not asking for much. Everyone complains about the que times and the tank shortage, why not find ways to fix it.
Fake tanks in veteran dlc hm content is non-existent in pugs, no way you can do veteran hm dlc content with strangers without a tank. This is what I was mostly aiming the once a day reward for tanking using the LFG tool like what other MMO's offer. So just like how you get a random dungeon daily reward, you would get a random daily reward for tanking veteran content using the LFG to help fix the que issue.
Honestly if there was better class and race parity, that would go a long way to adding diversity.
How many Templar Tanks are there? How many Sorc and Nightblades?
They exist but the incredible class imbalance makes it almost as if they didn't exist. I don't want them to be identical but those classes need more in their toolkits.
