Just afraid of an immature SEA community, like what happened with sGE.
Initially for GE, at least 30% of it was made out of Americans/Europeans, and there was a nice mix. After SoTNW was announced to be free though, they all went back to the USA server, and the community was dominated by Singaporeans, Malaysians and Filipinos.
Before that, the attitude was "BAN ALL BOTTERS!"
After that, it became, "So what if they bot? You're all just jealous!"
I'd honestly rather hop onto the American servers if it weren't for the latency, and if it weren't for the fact that all of my local friends are likely to be on the SEA server.
On top of that, IAH is so afraid of losing paying customers, they don't dare to ban some of these botters. -1 for IAH.
