In terms of raw talent, i think konfig was one of the best. To be one of the absolute greats, u need to have talent and work hard. Just like simple and zywoo. I dont think device is as talented as konfig. However he works hard and his team puts him in a great position to get a lot of the frags. Im not saying he isnt talented. He definitely is, but imo its his hardwork that got him the status of one of the best players in the world.
Anyways, like i said before about konfig, his raw aim is up there with the likes of twistzz, niko, etc. So it just would be great ti see another player of that level to come back to the pro scene.
