In FFXI certain jobs were excluded or picked last for content. Puppet-master was objectively worse than all other DPS classes for a good 2-3 years (possibly longer, I stopped playing it at that point). It had nothing to do with bad players at all.

On the other hand, Warrior was objectively worse than Paladin in XIV and it gets fixed within six months, and Dragoon its going to be balanced shortly.

I don't think it has anything to do with the strict trinity system though, just that XIV developers seem to be much more pro-active.
