This Mordekaiser was using an obvious map hack. He had a cloned version of himself that he could port to at will all across the map. Every time he was about to die, he would "dissapear", leaving a ghost-like version of himself that would just stay there, invulnerable. While his ghost version was still there, he could be across the map, having ported to an ally of ours to finish them off, Shen style (no, he didn't use the summoner spell port). When we asked him about it, his teammates just replied "oh, that is just your latency"... me and my 5 teammates did NOT experience latency, we saw an obvious hack being employed. More comments from his team led me to conclude that they were in on it too.
When we demonstrated proof that he was "two places at once", he said he was simply using ghost. I have played this game since beta... ghost doesn't give us 4000 movement speed, last time I checked.
I bring this to everyone's attention in hopes that Riot can find out how to stop this. Also, everyone please be on the lookout and provide Riot with as much evidence as you can. REPORT IT! This is a great game. I don't wanna see it burn in flames because some people actually feel some weird sense of accomplishment, having hacked to "win".
why not take a screenshot???
