Aggressive Launching

Is it allowed to launch beys aggressive?  I mean, to launch the bey intentionally with a drift / swing movement so that it flies over the stadium and directly hits the opponents bey?

In the round TT stadium that's not possible, but on big oval stadiums it is.

I ask because a friends always does that and his metal disc damages some of my layers.

Are there official rules for launching? Are there tournaments with oval stadiums where this could be a problem?

I fear that competitive players dont take this problem seriously because they say Haha hasbro players with Cross collision stadium and their problems ;-)
