Same here.
Nice idea to give us 14 days extra IP Riot but I'd rather you not give us things and fix this problem instead. I played one game with this new split server and had normal ms, but the second game gave me 350+ ms, which is pretty unplayable.
So, please! Fix this, I was really looking forward playing now with the extra IP and the new servers and now I can't experience any of it because the lag makes me useless.
