I agree with everything Alhanelem and Antipika have said up to this point. OP and some others are blowing things out of proportion.

Of course, OP's attempt to downplay the importance of gameplay irks me a bit.

PS: Comparing reaction time requirements in a modern MMO encounter to that of a fighting game is very silly. Please stop it.
PPS: Some of the JP posts on the Japanese forums about this are downright mean. It's not like they're shedding tears at the possibility of a split in the community.
