Right from the start I was able to "do stuff" without getting smashed. In addition I think the same thing applies to watching it. In the beginning you only see 5 people beat the hell out of 5 other people in fancy colors with lots of "BOOM" and stuff and the longer you watch the more subtle things you see.
The thing I really don't like about it: The attitude of many players you meet online is just... let's say "not very pleasant" . I hate flaming of any kind. It can ruin a perfectly normal game to the point that I just want to set people on fire and keep them long enough alive so they would feel the maximum pain for the maximum time... (Sorry for the little rant. :x )
