For garment, Raydric is most useful if there are any champs around.
I wouldn't recommend any water armors because you'll get pwned by Jupiter Thunder and Whitesmiths with SQIs (Mjolnir has wind property). OL is best slotted in water armor, but you wouldn't use it against anyone except champs.
Maybe Marc wind armor until you reach the emp, then switch to Tao gunka when you turn on frenzy and attack the emp.
MDEF gears + GR works even better, especially if there are champs and creators attacking you. High MDEF helps against frozen status and magic attacks; and GR allows you to tank Asura Strike and AD.
It really depends on what enemies you are facing and how many of them..
Oh, and I forgot frenzy reduces your DEF/MDEF to 0, so it would be best to switch to Toad shield before using frenzy XD
