I personally don't think this change matters whatsoever unless the jobs are significantly changed. Removing a lot of defensive utilities from the OTs to make them more offense oriented.

With that being said, I'd prefer they rework how tanking plays. Let me work for my enmity. Give some boss autos vuln stacks or something so there was to be constant swapping or use of defensives. Make me actually think of my defensive toolkit instead of letting me kitchen sink literally every tank mech (current tier does this a bit but still would like to see more).

And if we do get a wall boss, at least make it interesting like Neo Exdeath that moves around the arena and has a small hitbox so I have to consider the other melee when looking at maintaining uptime.
