About the kicks.
I had this same issue. The only solution I found, is to delete everything connected to your mouse.
For DeathAdder elite there should be a program to control the LED lighting, delete it.
I've done the through Control Panel, searched for Razor (windows 10) and deleted it.
Now the game doesn't kick me.
About the latency, as I know, if your latency is higher than 300 (or even having some spikes/jumps in latency), the game will kick you or you'll have seriously lag for few seconds.
