I did the repair installation... went in, and played ARAM custom game thinking it might be a good test for ping issues. No ping spikes that I could tell. I go to play TT with my 2 friends, and 2 games in a row, terrible terrible ping spikes throughout the game.
I'm a customer, who has spent plenty of money on this game ($100+) and I have much more to spend before its all said and done, however this ping spikes issue is the most infuriating issue I've ever had. I'd rather the game just not load or something... I hate the feeling that I've lost because the game is screwing up. Its so bad I am considering QUITTING. Seriously, I have put in all this time and money into this game, and now its become so unplayable that it lets me get into a game, lets me play a little... but as soon as the fighting starts... PING OVER 9000!
I don't know why, but it makes me so angry, incredibly angry to have this problem, and have no solution in sight, no response from Riot about it, no place other than these forums to come and scream about how much it upsets me. Its just a game, but its still my favorite right now.
Riot, please find out what is wrong and fix it. At least come into the forums, admit that you are aware that HUNDREDS of your customers appear to be having the same issues, and admit you don't know what it is, but you will fix it.
Have us send in DXDiag files, or something... don't just keep it broken and say nothing.
