Am I the only one on PBE that finds this is very childish? Granted I think it is childish to do so on the regular client, however it feels even more distasteful played on the PBE. Are we not here to test new things, find bugs, and improve the quality of the game for players? Why are people tearing each other down over a PBE game?

Agreed.
I played a normal to see what the PBE community was like, and the majority of PBE players in normals and such would appear to be level 10-20's. It's a shame, they're just using the game for their personal gain, exclusively.

I do agree with you both, but you cant help the helpless. Everywhere you go there will be ragers and trolls in every game you have to deal with real people. Sometimes you just got to ignore it and move on. It may be hard but you cant help that fact. I suggest you find some good people to play with and keep the circle small and simple. It may or may not work.

Just puttin' mah 2 cents in.

I don't believe it is childish. I am not a child yet I talk trash all day in the regular game. I believe it is rather funny when I get called a noob though. Due to the fact that the majority of the people suck (be honest, the majority of the people don't know what last hitting, or team fights are and only playing in beta to try out free things) I feel that it is unneeded to talk trash due to them not being able to do anything useful for their team. If someone is good I think it's fine to talk trash a little bit in beta, but you really can't expect that much from the people playing it...
