This would include a change in the actual game engine so it won't be implemented
Says who?
I hope when the bugs in the game engine will be fixed (finally) there should be some possibilities to add a few tweaks. I would like to have a designated scorer for certain situations.
He is right... In a non-relevant way...
Every change in the way the matches are working is... a change in the game engine.
BUT, it does not say anything about is it easy or not to implement, etc.
In this case - taking in consideration the requested shooter preferred by the user is not that hard to add.
