I think another huge plus of this generation's frontier is the fact that you gain so much BP when doing wifi. I've wifi battle towered with my friend a couple times, we kept losing on the 3rd round, 21st trainers lol...
Anyways it's like 1st round - 8bp, 2nd round - 9bp, 3rd round -12bp 4th round - 14 bp, all other rounds are 14bp. Something like that, it's really high.
