We did have more of that. There is a reason the devs moved away from that.
Said that, maybe they will find a way to make it work properly this time. Let's see what they are cooking.
There is no need to apologize. I also fully understand it's a very difficult concept to pull off if "unique" jobs are also a requirement.
I actually believe it's a "cursed problem" in game design, meaning a problem which puts different fundamental game promises in conflict with each other. Such problems cannot be really "solved" cleanly, they can be only compromised around.
My point with the first statement is that many players, me included, have issues with how they moved away from that. Ironically, there's now an imbalance between balance and diversity for a lot of players. There's a reason they are changing it also.
But for sure. I hope they can execute their ideas better.
I think people are taking this too seriously. If PLD gets to keep Cover, Clemency and Passage I doubt the other tanks are losing anything that they normally have to main tank.
I think their additions just aren't going to focus on main tanking.
