CTR is way too pivotal on specific items and too pointless on others. Some items need their base charge times reduced, and CTR as a whole needs to be toned down a bit while still being more powerful than flat damage.
Bombs especially are extremely reliant on CTR compared to guns and swords that utilize ASI.
Ctr is pretty much... The only thing bombs need. I would agree putting a lage delay on the brandish charge time, but everything else is pretty balanced. Well, except for the volcanic pepperbox... Something that small should charge faster than the average blitz
