Well, I set it to DL and install when I went home for lunch today. Hopefully, I can pop on there sometime tonight. Are there rookie rooms or anything to help me get my feet wet or do you just jump right in and go all out?
There are practice games that you can use. You can play those with other people or just bots. However, the bots are a terrible misrepresentation of what actual players do in game (they're really only okay if you are trying to learn a character's skill set imo).
Yeah. You can join practice games much like how you would join games in WC3 or SC, they have names and such which will have noobs, testing out new char etc as names, and when you join a game you'll see the levels of the people in the game (level 1 is noob, 30 is generally won 100+ games I think)
