Now the problem I have with not having east coast servers is that I personally HAD an 80 ping before season 4. Now its at least 105. Now you say thats not to bad....well the problem really lies with the Latin American North servers. Recently during one of the down times of the NA server or where my ping was a minimum of 200 for a very brief second before going over 500 I searched for answers and what I found was LANS (yea that is a run-on, but idc lol). The ping on that server was 40........40!
Thats ridiculous that if by simply switching servers that I can have that drastic of a change. Going from NA to EUW on a normal day yields a +20 ping when going to EUW from NA, but at the time was 100% more stable. So its hard to really completely defend the case when there is apparently an "east coast" server already, but it would send a vast number of players someplace they probably shouldn't be.
Personally I don't think the ping is that huge of a problem. Watching Nightblue3 playing he has a ping similar to my own so I know that its clearly not the ping that causes bad plays or misclicks since if he can be a challenger lvl player and live in the midwest then its clearly not right to say that all the best players are on the west coast. If anything I would argue that playing with a higher ping actually shows more skill overall.
My real problem has stemmed from the lack of stability that has plagued the NA servers recently when others have provided better reliability to me personally an East coast player. I personally would like to see something done since most of the players I've seen recently having problems have been east coast players as a whole, not exclusively though. I just feel like this may help make the connection more stable for those on the east than those on the west.
