I'm going to take Summoner and Puppetmaster both to 85 once the Version Update arrives. I'd do it now, but they're just barely 76 and I'd rather only drag them through an Abyssean party (hopefully) once rather than twice.
But I'm a little curious...what do people invite Summoners to do in Abyssea? Hastega and Cure? Damage BPs? I think pet kills all counted as Ruby light (which nobody ever wants) or something? Anybody with some experience they can share please post a comment.
