Why can't we solo old content?

[Moheeheeko]

But seriously, every MMO I played before allowed you flexible groups (with max players set in stone though) and you could solo thing if you had the nuts/overgear to do it, so why not in FFXIV ? Why are we so adamant about it in FFXIV ?

because those other mmos didnt have every class on the same character.

In those games if you got gear from a low level dungeon, it was completely useless (save wow after the transmog patch)

this is not the case here.
