What about the ping? I've actually never played on korea servers, but I imagine lag could be more of an issue than it already is on West? i'm from east coast and if i play vs anyone else outside of east coast in 4 players + games we can hardly get anything better than TR8 (and I have 160 mb/s internet so I doubt that's the issue). I see lots of ppl saying it's perfectly fine to play on TR8... but really once you get used to TR16 and + with low latency, going under that is highly noticeable for micro. You actually can't muta micro properly below that and others tricks doesnt work aswell. This doesn't break the game on fastest because it's mostly macro but on standard maps this literally makes some build orders not playable.
