about the damage, yes it is quite weird (i am not sure about your level) but at a certain level it gains like 25% chance to crit so sometimes you get a nice huge cirt whit the 2.2 dmg modifier we cats have and sometimes you get like only less then half, and this also depends on the energy becase if you are 35 enegery or at 70 it will do double its damage.
so depending on your energy pool and wheter or not it crits it can do about 4 times more damage then a normal non crit FB whit 35 energy
(while leveling you dont need to pile up energy tho, you cna jsut do mangle mangle mangle bite and goto next mob :P)
