Not that crazy but it is an idea. I'm ok with rejection

.
The current way to play the game is to go
Axes + daggers or Swords + staves or off class casting.
You can also use clubs on feeder + paladin.
So paladin is good with axes, clubs, tanking and off class casting.
Why not switch monk and paladin positions

?
Make monk 3 doors and make paladin 4 doors. The more diverse class would prevail for longer.
This would make people who use swords go Fighter (swords) Samurai (swords) Monk (staves) Paladin (swords) Ninja (swords)
or
Fighter (axes) Samurai (daggers) Monk (daggers) Paladin (axes) ninja (daggers)
--------------------------------------------------------------------------------------------------
-This would make passing between monk - paladin and ninja more rewarding. Right now most people use exactly the same gear for monk and ninja so passing to ninja isn't so rewarding.
-This would increase the usefulness of clubs, swords and axes without devalorizing daggers.
-This would make healing for groups, tanking for groups, etc. more viable in early and late game seasons.
-This would result in more build diversity and consequently more fun in my opinion.
-This would make people consider off class casting + tanking and give more value to medium/heavy armors as well, due to the amount of time you might would spend on paladin.
