Primary attack and melee attack while similar are different functionally.

Melee attack will not be changed into cats claws during fortunes favor , allowing you to more smoothly combo/cancel the attacks at will .

Personally I bound melee to right click and kept primary fire on left . It’s a game changer . I use a similar technique for rogue rarely to hold her kick attacks after she flies.

But for black cat I’m doing this all the time, every game, every fight . It just makes things easier .
