The famed balance issue.

[PureNoob]

Tell the newbs to stay at the base and build.

How about letting the noobs die a lot like in other games?

Because that's the answer of "How enemy team got s2 so fast?  "

Haha, I couldn't have said it better myself

The problem is that noobs are trying to have fun. Maybe they don't like to build and when they would start building, people start whining about bad building.
