I'll give him a year before Tyrant Dave fires him or kusang aalis dahil sa sobrang ka-buwisitan 
Megadeth is a brand,an institution in heavy metal. So it is Dave Mustaine's prerogative to see his musical vision into fruition. His success wasn't overnight so it his right to take HIS band into whatever direction he wants.
Let's say you have a reggae band named Ngongong Hikain. You wrote all the songs,the melodies,the lyrics. You have an M.O. set in stone as to how your band will operate. You hire this guitar player, Boy Kurikong to play in your band.
What will you do if Boy Kurikong plays 12 fingered tapped arpeggio solos in the middle of your reggae songs?
If you fire him,then Boy Kurikong will go on social media and other online forums to say that tyrant Kennyken fired him because his playing was too good for the band.
