sorry I'm joining this thread late but I've read all the posts so far..
I spar better on PC than I do my 4G iPod, obviously there are some advantages.
For example you cannot honestly tell me a pc player sparring a 2G iPod player is an even match, theoretically even if they both had the same "skill" level it would not be fair..
in the end it is about latency and lag, idk how it works but other big name games are able to overcome this and put everyone on an even playing field..something we have not seen in graal
