I am pretty sure no characters on WoW are perfect. GMs overall
have the ability to do anything which may be considered perfect.
Players may have the best gear in the whole content/game, but they
may lack of skill or opposite. Even if a player is skilled an
geared they are not the best on WoW. If you mean the perfect as in
good gear, level 80. You can try playing on the BLIZZARD ran PTR,
but it is currently closed and there are several requirements you
need to meet in order to play.
