I would strongly advise against this form of abuse of a flawed system, since it is vs other people in DZ, and also something that Cheathappens feel is not something they will allow their trainers to do in mp games, or they at least stop the trainer if found to be working in online gameplay we had the mass effect issue with that coop battle thing.
But it is something people can use at their own risk of course they are grown people, but yeah i also hope they plug this oversight asap to avoid some random dweebs in DZ going on a rampage.
Agreed, hopefully there'll be a proper "offline" solo mode so it'll be easier to make and use a trainer. Guess, we'll just have to wait and see.
