RGL recently implemented a fix to the deathcam bug that tracked your killer through walls leading to additional and unfair info gained (a good change). Additionally they plan to survey future competitive fixes going forward.
going forward here are the changes that I am currently advocating for and that i HIGHLY SUGGEST you vote to be implemented when the survey comes out
sm_projectiles_ignore_teammates 1 - projectiles not being blocked by teammates is a no-brainer to me, and in my opinion the game should behave like this by default. RGL should have implemented this as soon as it was released.
sm_override_pipe_size 4.0 - this is the one that reduces the iron bomber hit box to a 4x4x4 cube instead of the unintended 8.7x8.7x8.7 cube that it has by default. This fix was very clearly popular as evidenced by the recent threads regarding the iron bomber, and RGL should have implemented it for this season as well.
please vote for these to be implemented when the eventual survey comes out. tyty have a good day
feel free to discuss any other of twiikuu's fixes here as well i guess, the list of them can be found here: https://github.com/ldesgoui/tf2-comp-fixes
