Do not force level caps on content - You segregate the player base

[Jocko]

Stuff can be hard without level cap

Not when the party is 25 levels higher than what the content was designed around

A friend of mine who started playing recently was pissed because there was no one around his level to help with baby Ifrit, and the group he got killed it before he finished watching the cutscene. He was looking forward to something that wasn't leves, and it was ruined. Level cap would have fixed that issue

Besides, XI got gear scaling, which would imply XIV would have gear scaling, so I think that's a moot point
