The time cost of the beta Client is too damn HIGH!!
Anything that has to do with me making a game is extremely slow. It's okay until I actually accept a match but the process is too horrendous for me to actually use it. I have almost dodged quite a few games because the client is abymal. It's snail paste and I can't tell what's going on and its hard to change masteries.
But worst of all god forbid someone dodge. When they do the client is slow getting back to the lobby that when I should be instantly queued for and accept another match the game already queues me and prompts me to accept but it's so slow that I can't do that and have to wait in the lobby all over again.
