To be honest, MadLife has fallen off pretty badly in Season 4 in my opinion. Back in Season 3, when it was still unlimited wards, MadLife was good because he warded really well, but even so, Mata was practically on par with him in that aspect, but in terms of play, I can't agree, Mata has always been better in my opinion, and has continued to do well in Season 4, MadLife kind of lost it.
The MadLife "standard" is pretty much a residue of his best days now, just like the Faker "standard" is for mid right now. Anyone who has been up to date with OGN will see that Faker has been severely under-performing in Season 4 compared to Season 3, not saying he's bad, but he's definitely not doing his best, yet everyone is still calling him the best, and that it's SKT K as a team that's dragging him down, when in fact he has lost plenty of 1v1s during laning to those he easily beat back in Season 3, the same is with MadLife, people are comparing others to the first person who became "legendary" at a particular role in their best days. All I'm saying is, MadLife is no longer as good as he was during Season 3, personally, I just think he didn't adapt too well to Season 4.
