scratchhI think the iron bomber hitbox would just be better for both of the launchers as every demo already uses the iron bomber and its a considerable buff for a class that already struggles against scouts and soldiers
It should be consistent between all the launchers, loch n load and loose cannon should have the same hit boxes as well (or perhaps arguably the loose cannon should have bigger ones since it's a fkn cannon ball and the weapon sucks lol)
Also I feel like the iron bomber having such larger hitboxes was definitely a glitch and valve did not intend them to be so absurdly large so if they do patch this I doubt they'd change them all to be like iron bomber, especially given pubbers still complain about how demo is overpowered and they don't particularly seem to care about competitive (or meaningfully changing the game at all...)
