What is the ping required for KFM?

[fate1saber]

I have heard people saying as long as one has a ping of below 110, he should be able to perform KFM's 3rf combos. With ping test i have around 90 ping to the game server, but whenever I tried, my combo never connects as it should be.

An example would be V->3rx->4x 3rf, there will be around .1 sec where the opponent isnt stunned and therefor, I would get punished for it.

 

Should I even bother with KFM?

 

ps. seriously why isnt server in Chicago like other big games?
