Cannon Shockwave and Backfire moves need buffs

[AviatorBean]

These 2 moves have always been a lot less viable than the mortar volley, The mortar volley has range and no recoil damage when full like the other 2 planting moves, & it does more damage due to scaling for each ammo instead of every 2 ammo. I find this really confusing because the harder and riskier to utilize moves do less damage. Just making it so the damage scales like with mortar volley would work fine for making them more viable in my opinion

Sidenote: I'd love a cannon variant based around these moves, especially backfire, it could be like rocket jumping
