^contextually we're talking about sticking to the design in the form of DPS-Support Hybrids like Bard... it wouldn't disrupt the game's core design/structure much at all. And I'm saying balance is a must.

Just because you have a Bard-alike that applies party-buffs in a manner that's less passive & global doesn't mean you're breaking the game if balance is kept in mind which I'm arguing is possible.

Making a Job who's focus is less on enemy mobs spamming it's attacks can be implemented properly without breaking the game.

I feel like you need to go back 5 or so pages & read through much more carefully, the context seems to keep flying over your head.

As a note, the topic of conversation switched from breaking the Trinity to diversifying it a while ago.
