I think it'd be a fun idea to have some sort of arena tournament where all the characters participating can have no class leveled higher then one. So it'd be a bunch of 4x1's.
This gives each player a lot more options and fun potential by being able to create a character for the sole purpose of this tournament. And even though the characters are only lvl1, there's plenty of strategy involved starting from picking the classo to making the best use of all your lvl 1 abilities.
I'm thinking for eq, anything the character can wear, but no holy eq.
Alternatively, this can be a 4x3 level tourney if people wanted a little more diversity in their characters. Having 4x3 characters separates out the melee from the magic users a little more
Just a fun idea
