bif we put riven's kit is unbalanced, i will show you why

I am riven and Fiora main and I am also a bloodborne player, and here's something just came up in my mind a few days ago. If we put riven into bloodborne, riven will probably be a strength build player, her weapon will be something like a moonlight greatsword or kirk hammer, she should have lower mobility because you can deal massive AOE and smash enemy on the ground hard CC). riven also have super good cdr while if ur in bloodborne strength builders have to be very careful with their stamina But riven has shit tons of mobility in a league of legends

so summing up if riven actually exist in bloodborne, you never need to do a huge swing before you attack , you never charge attacks to stunn enemy on the ground(you never need a teammate to setup to land the hit for you), you never need to risk being punished after you miss your attacks because you take forever recovering you stance because you can just walk away. you don't need to worry about your stamina because you cdr is that good.

Let's take a look at fiora, fiora on the other hand, is more like a skill build player, her weapon will be something like a blade of mercy or rakuyo, which has less cc, less aoe but a lot more mobility and much more reward than strength builder, but in league of legends fiora has less mobility than riven and deal way less damage than riven on a even trade. fiora's block can also be dodge unlike bloodborne or draksoul.

the mobility difference mainly comes from the cast time of each attack and the delay after picking up your weapon after each attack, but riven has fast qa, hence there is no cast delay between each hit, riven can cc hit and run do more damage than you in lane, in team fight pulling off aoe much easier with out any setup but anybody else. If riven i behind that not a big deal, if fiora is behind you useless
