There isnt any worthwhile content that can be used with the companion system yet but when it does, I'd like the companion system FFXI had without the summon time restrictions. FFXIV had that, in a way but they didnt help you in combat at all, just insert themselves into cutscenes and do the talking instead of you nodding and huhing (weird huh?).

Anyway, basically I want 'retainers' for combat that you can give items and tell what to wear. Make them only able to wear craftables to. Might help the market a bit and lets players see 'human' characters run around in anything other than myth/ct/allagan combos.
