Homebrew is rad, homebrew options that are accidentally stronger than official options are bad and homebrew options that are intentionally stronger require one hell of a game designer to keep the game reasonably balanced.
The monk isn't homebrew, they just used the 1d20 in order method of stat generation. They got 18(+2)/20/20/14/20/10 and a CL feat. Honestly, MADness is only thing holding a STRonk back.
