Vayne is going to completely break the game next patch.
The new
has an effect where after you use ult, using a basic attack lowers all basic cd by 1 second.
q has a 2 second cooldown
Next patch
will build max cdr and reduce her q cooldown to 0.2 seconds during her ult.
0.2 seconds is less than the average human visual reaction time, meaning by the time you react to vayne appearing and abutting you, she is already back in stealth.
What makes this even worse is her q is an auto reset, meaning she doesn't even have to build attack speed and can just build damage and lifesteal and completely destroy everything.
I expect a vayne build like this
If you don't end the game before she gets
(which is about 15 min), you auto lose.
