I don't remember us needing gear at all.
Think of it like this: a pld is supposed to tank, right? So what should he gear himself towards? Obviously the answer is gear that'll help him enhance holding hate and/or damage reduction. Depending on their SJ (just like smn) they situationally place in gear that'll help their overall performance.
A summoner is supposed to, y'know, summon, right? So obviously we're going to have some form of gear that'll help enhance that (AF, Auster, Smn. Torque, etc.) But then you'd have to think realistically and buy hMP gear to increase the frequency of BP and then account mp you'll be using for other roles (healer). What I just listed is the traditional way of SMN, but I'm not knocking the melee aspect, I just don't gravitate towards it. That's why I'm annoyed :P.
