I enjoy FOmar since it can basically do everything good enough for what it is, a mix of all classes to an extent. I also just love its ATP. It's ATA is something to be desired, being the lowest ATA of all classes but, I still enjoy the class as much as ever.
Its level 30 techs help it a lot.
Godric's Cloak gives 30 to all stats iirc, which helps with FOmar's low ATA, at a sacrifice of resists. It also looks great in its dress-kimono thing.
It can run TTF in a fairly fast time,
Can solo ROCT if done right,
Can do RT in a slow, but ok (to me), time. (I've yet to improve this one)
I should try FOmar with other, not as "main and farm-y" quests and see how it does. My second favorite class is probably HUcast bc traps and op. pls giv FOmar df ;^)
