Rapidfire cannon is already too strong, sword of the divine is already too weak by itself since phantom dancer singlehandedly makes it negate the champion that built it.
Sword of the divine would fit the thematic/need pretty well.
Alternatively give it to the cursed blade as an on hit/on spell debuff.
Remove phantom dancer 100% imunity to crits, make it a 50% and remove true damage from vayne because it is enough of a cancer in sr, we do not need another one in tft if u rly have to have true damage in tft, swap fiora w with q and give it true damage
Putting it on Sword of the Divine would work, considering its other passive so rarely procs if ever. It would certainly give it more of a presence for ADCs, considering it's made up of the two ADC items and yet is currently rarely (if ever) built. That would mean Sword of the Divine would synergize really well with IE, but that requires 3 BFs, so I'm not too worried that would be spammed.
I also like the idea of moving it to Cursed Blade, but mostly because it's another of the super rare items, and they need to be buffed somehow.
Completely being able to negate crit is absurd and PD most likely needs a nerf. I never build crit items anymore for that very reason. I don't think you could give an item 100% crit (essentially) while also making attacks undodgeable. It seems a little too overpowered in my opinion. I think RFC is fine but its build-path should maybe be different, though. You raise some good points and I'm sure that item balance and abilities is something that Riot is looking into.
