Meh, the only reason I don't tank often, it's because I have nothing else to tank for: after I do my expert roulette I'm practically done with tanking and I rather spend my time either learning Suzaku Ex or using the roulettes as a DPS for leveling them up.

I'd be glad to tank more often if I had more incentives, but I just don't have any! And it's the easiest class in the entire game too so I feel so bored after doing absolutely nothing!
