I didn't actually have any problems with any of the admins. I beat Lovrina with an already weakened team without saving beforehand, snattle I didn't have any real trouble with, the only problem I had with Gorigan was his hypno. It wouldn't stay snagged and each turn it had it knocked out another one of my pokemon. I finally snagged it with my last pokemon in the red. The only one I had a problem with was the one on top of ONBS(forgot his name). He took a couple of team rearangings and item attachments and suprizingly when I beat him finally, I only had a few pokemon knocked out.
The second time around, I beat lovrina with a very weak team of pokemon, the next wasn't too hard, and as for the other two admins, I haven't gotten that far in the game yet.
