very bad suggestion
in fact you know the history of mu? since leaving the first versions of mu (0.97) the ELF, MG and SM cant kill the BK
in version (0.99) was add to the char of DL that could fight against BK and even kill him
in S3 e2 was add the only female char (summoner) that can kill the bk and all class
then given more power to MG so you can fight the BK but still very difficult to kill
you asking something would go against the history of MU
your suggestion realy don't like at all
is better to play so and continue to enjoy in addition to allowing each class to do its thing.. which is why they were created
