An ultimate that gives you invisibility, bonus damage, and a speed increase will never be fair

Problem? Apparently. Bloody casuals.

So you balance the rest of their kit,

: now there' s a smell you can feel!

vayne's ultimate is not really her problem...it's just added unnecessary stuff in her kit

Twitch's basic ability does most if not more of what her ult does with both a reset for it(now) and a large attack speed increase(damage) and even move speed bonus

: Ultimate?
