It is a good thing there are constructive discussions regarding the gameplay but I dont like the way you do it. There are so many opinions as there are players, so why dont you just
- fork teeworlds
- code the feature you want ( reduced laser bounce-damage )
- host it
- play it
and then realize the bounce should not be removed. Further discussion won't lead to any usable output. I mostly agree with the answer of Magnet on the qi forums. And arguing that the bounce makes the game random, and all this crap about competitive gameplay are stupid. All games have some uncompetitive stuff or luck factors ( which laser bounce isn't !!! ). If you want competitive gameplay play with hammer only, because all weapons can be used to make "luck shots".
So to sum it up for you, I think the reduced damage is a good idea, removing the laser, increasing damage and reload are NOT, replying to this thread without adding something to the discussion is NOT a good idea.

Finally a video that shows the fun side of teeworlds. Good job.
