They desperately need to prioritize and add vanguards, nobody wants to tank
The best way to fix this would be to offer more tanking characters IMO.
Edit: or better yet, why are they even in games at this point anymore. Nobody wants to tank in overwatch, nobody wants to tank in marvel rivals, nobody wants to tank in most games that tanks are offered in.
It makes no sense why we keep shoehorning these archaic design paradigms that so clearly should be aged out and replaced with something more innovative and interesting.
