I do think Axl can come back to 2010 levels quite easily and to 2006 levels if he commits to it.

Axl from 2011 on seems really mellow and to me he seems to be under medication. Perhaps come anti-depressives or heavy anxiety pills...

All the memory loss in Rio '11, the fiasco at Bridge School Benefit... The low qual performances, the bloated persona and seemingly careless attitude - damn, he's not even running around during Paradise City anymore... Some people say it might be due to leg/back problems, backed by the video of him arriving at Rio after the show this year - cause by that edema he had due to falling on his back on stage. I don't know, perhaps pain medicine can cause the zombie Axl.
