I'll do any of the following for FG:
Get you (x) amount of credits in (x) amount of days.
Play any playlist you'd like to have a good K/D or Win ratio in, I prefer MLG but will play anything.
I recently started playing Arena out of boredom, and got a 6% onyx with a 50/53 win ratio and over a 2.0 k/d. So I could probably get you to 1-3% relatively fast if I put effort into it.
I talked to a JM and he said these services should be fine, but if he was mistaken please PM me and I'll make a post explaining to not post anymore and to let this thread die.
