^ You know, they could do the same thing Guild Wars does.
In Guild Wars, There are 10 classes.
However, you could combine these classes into hybrids. For example, you could be a Warrior/monk, or a Ranger/Monk
With that freedom, there were tons of hybrid classes you could be, not to mention the pures.
Or, they could do what Runescape does. There really are no classes, one person can pretty much do anything. (Melee/Range/Magic)
Don't let people make you feel stupid for being yourself; do what you love to do and what you think is cool.
