This is what it looks like when he encounter elite packs with vortex/knock back affixes
Look closely on his latency bar.
It may look like he is pushed outside of the game map but in my view while playing with him when he is lagging he is not. Ghost hack?
Same as when his character switch places, for example he is experiencing rubber band lag, I may thought he just suddenly stop but all of a sudden disappear and switched to another location. Why? Because he keeps on walking/vaulting(DH) even when he is lagging. Do they even know rubber band lag is switching character back to previous location and that its another way around to look his view and other players view. Teleport Hack?
Last, he is always online playing and grinding. When he is about 500k exp away from level 100, then he gets banned. Why? Maybe he became human bot that blizzard suspect him as bot user. Bot?
Does anyone knows what "thorough" investigation Blizzard Support Team mean or done?
This is a very unfair decision from blizzard team so if any of you know what, how or why would blizzard do this please comment.
