EDIT - sorry don't think i explained that very well, if i have one on line profile with a level 50 siren on, can i level up another toon on the same on line profile or would i have to use a second (non online) profile to do it

Nice tips, on the power levelling one though i take it you can't use both players on the same gamer profile?

No worries mate, in UK so will be on at some point over the weekend, there is about 30 odd weapons on there i'll drop so clear some space lol
