I wasn't talking about league games, I'm talking about BnG rules in general. Anyway if you are playing league game, you shouldn't play it cheap either. And my opinion is that the repeating shots one after another (after hitting the opponent) is cheap and lame thing to do in BnG.
If you allow repeating shots, who will ever bother to get any skill in this scheme in future? Most of players will just throw 3 sec nades constantly and that is not the point of BnG. As I said already, if you do that, change this scheme name to NtD - nade to death.
BnG should be about skill in throwing nades and using zook. That's why only zook and nades are there in weapons.
