I'd like to suggest a "slap" attack with minimal or no damage. It would be very short ranged and wouldn't provide any knockback or push.
Basically, it's purpose would be to hit switches and break blocks and minerals. More then anything, it's purpose would be to help pure bombers with these tasks. It can be annoying to have to wait a second or two to hit a switch, and it can be quite aggravating getting minerals that are spread apart. Perhaps it could also be used to cut grass (helping gunners as well) but mainly it would be for blocks, switches, and minerals.
Thank you for reading my suggestion
(EDIT: Changed the title to give a better impression of what the suggestion is)
That might be a viable option, but I think that there are already swords that can do all that, and which actually do damage.
I already find that it can be frustrating not having a sword, especially when breaking minerals (especially with 2clip guns/slow swords), but then you could just use fast/3 swing swords to do the job.
EDIT: Wait, maybe I read that wrong - did you mean this slapper would take a weapon slot, or would it be separate? Because if it isn't, then you would have my +1 :D
