By the way Torpedo will now can roll on the ground farther than before (remember Splatoon 2 lol), so it will so cool to do the Torp-Charged slash combo.

Personally I don't think so but I do think more weapons may be merged together or given the dualie squelcher treatment, that's what I hope for personally. Some weapons feel very outdated now that s2-3 has pushed for more complex options.
Most obvious by a mile is goo tuber and squiffer merging.

Besides Splatoon
