On phone, can't wiki edit, not sure what info is staying or not. But fishey's comment on patchy being useless for trash is drug induced. While her speed does indeed prevent her from nuking down enemies that are fast, she generally CAN outspeed your average mook like knights, sorceresses, etc. Her elemental variety really helps with trash too.
When you are underlevel playing with defensive builds, in plus disk, you actually have trash get to make moves fairly often, likewise, her mnd allows her to continue taking 0s in that situation.
Honestly, those whole "sucks at, is bad, etc" comments shouldn't be thee IMO (except for reisen maybe =p)
