So this guy http://bf4db.com/player/1691654369 is set as clean since no proof provided.
I was checking him on metabans (http://metabans.com/player?i=Rm33) and there is a youtube video linked.
Check it out https://www.youtube.com/watch?v=1YhjJ8g3J-s&feature=youtu.be. I think one can clearly see how his health is recovering even while under suppression or fire.
Also seems to have a stats reset from fairfight when you check here http://bf4stats.com/pc/DICE-TIGER/history

Hope this helps!
