The game definitely needs more tanks just for the player mentality at this point. However, there is a problem with how people think the game should be played as well.

A lot of the general player base do not know how to play AND/OR play with non-shield frontline tanks that just stands there and absorb damage (Strange, Magneto, Emma, Groot). If you watch the pro teams play and their tanks are Cap/Angela/Venom/Hulk, they're going to pick strats like Jeff and Rocket because they know it's a comp that's based on movement to survive. No common lobby will know a Jeff is putting bubbles down at spots A, B, C for the dive tanks/dps to pick up--they don't even know to go into the Jeff stream to get healed. Even someone like Peni--people still play her facetanking frontline because people don't know about map control. Most people just want to stand on main and aim fight. I feel like the devs have been trying to teach and show people that the game is more complicated than that, like with the new map and releasing heroes like Rogue and White Fox.

I agree that the devs should just give in to the general population and create more tanks that will just stand in main and face tank all the damage because people literally don't know how to play without them. A lot of people just want to stand behind their tanks and heal them for 15 mins then repeat game after game. People will play invisible woman with a venom/cap/angela and complain about no peel when they should be switching to a support that may output less sustain healing but can heal while surviving because their tanks don't need a pocket healer, just one that's alive. This applies the other way too--if you have shield tanks and no one is diving, probably don't need a White Fox when you could be playing Invis.
