sheafBut 'fixing' the iron bomber is most importantly a nerf for demos to protect themselves in DM settings
So I think that is less called for.
Without wanting to sound condescending, demo is a lot better at defending itself than a lot of people give it credit for - it's a very old way of thinking that demos are helpless lambs without a scout protecting them :-P Yea demo is worse at protecting themselves compared to a scout or soldier but people have gotten good enough at demo mechanics to turn losing situations into winning situations fairly consistently.
Banning iron bomber wouldn't stop that from happening, it would just make it happen like 5% less and it's because a pipe that shouldn't hit actually misses or the enemy isn't stopped in their tracks by the pipe hitting slightly earlier than it should. A demo can still outplay their opponent but they don't get it for free in some freakish edge cases.
