It is unfair, it really is, but you can't blame the players for it. I understand how the iPhone community feels about it, you've all been sparring and doing competitive activities knowing that you're all using similar devices. Then comes the big bad evil PC players and change everything. That's all that I personally view it as though, a change. As callimuc said, not everyone is good on their PC's and really the people that are most complained about (such as Rashard) are top players on the PC version of Graal too. I don't think PC players have that great of an advantage either. I can move a lot more freely on my PC than I can on my iPod, but some iPod natives find iPod controls to be a lot easier. We see more of the screen, and we have the ability to type and do emotes faster, but this "they move 10% faster!" statistic just seems fishy. If PC players have too big of an advantage, there is nothing stopping you from getting on one.
I lose to iPhone players, and I can beat PC players on my iPod. It's a case of adjusting to something that has been forced onto the community. Players don't enjoy adjusting to new challenges in a way that dethrones them in competitive activities, but that is really not a PC players' fault, it's the bad integration it has had in the server itself. They've tried to make it fair by splitting the GST, but whether that's enough is up to the members of staff.
