In every raid group I see it’s always got a chrono for the main tank, and the off-tank. Every other class has the ability to tank yet none are even considered for it because alacrity is so highly sought after. And when you see “chrono” on the raid LFG, you know they’re after a tank, and not dps.
It’s not like other classes don’t have anything to bring to the table either, guardians tanks could bring buffs, necro tanks can bring vampirism, warriors could try a hybrid PS tank, and so on. But no, the playerbase are so shortsighted it’s “chronotank or gtfo”
If alacrity could be changed in some way (like make it a self buff only), or just scrapped it would open up so much more opportunity for more players and classes to tank.
