I’m specifically talking Alliance side here where, let’s be real, there is zero reason to bring anything but paladin MT if you are minmaxing.
Every. Single. Phase. Paladin tanks have continually had their toolkits buffed and improved far beyond any of the other tanks in SOD, be it locks, rogues, warriors or bears.
Paladins are chunky enough to EASILY survive all of the toughest content whilst pumping mind boggling levels of threat out from the first global.
Classic tanking is all about generating enough threat quickly enough that your DPS never have to wait an extra global. As it currently stands and how it has always stood so far in SOD (Alliance), paladins are the only tanks that can pretty much guarantee this.
Not only that, but right now duo tanking alongside a paladin is downright miserable. You may as well not be there. Want to trade MT between bosses and try to be fair? “Sure, you can tank this one- oh crap I’m 30k threat ahead of you 4 seconds into the fight. Whoops sorry, guess I’ll take this one again.”
Zero reason to bring another MT. Other classes can work well as OTs in most cases but why would any progress orientated raid leader pushing speed, execution or parses with their raid team would choose any other class over a paladin? It’s so incredibly inefficient to do so.
Like, paladins right now even in single target builds are just so. Far. Ahead. I’ve tanked with other classes along side some of the biggest paladin tank pumpers on WCL, talking the top percentile here with a few 100s thrown in, and my god it’s staggering just how far ahead in threat output the class is when played at its peak.
Other tanks need some serious work, especially in the snap threat department (but some classes need a whole lot more than that), not everyone who wants to tank also wants to play paladin. The gap needs to be closed but every phase it seems to get so much wider.
