Gotta drop my 2 cents here since I've witnessed Azal kicking Madkiller for the exact same thing before as well, let's start with the video Madkiller posted,
We can clearly see the grenades delaying by 1ms, which shows there might be packetloss,
Secondly, ping is subject to isp, technology you're using, and not about what it shows, even if I use 64kbps net on 4g technology, I'll be pinging less than 200 or even 180, but with horrified lag at the same time, for an understandable example, you see your clanmate Nippon, he got less than 10 mbps net but he's from Switzerland, so he pings very low often but I've seen him getting kicked for high ping multiple times.
That what you're using as "evidence" itself proves nothing, we've all tested you and your whole MD clan, one by one, by or by spectating, Broly was asked to leave server countless times by Ryne even when his ping was normal, just to let you know.
Don't use wireless connection for online gaming, if you're using wireless then make sure that upload speed is good, that's all.
