Noooo. How about make the damned game so I don"t need any reason to have multiples max level characters in order to enjoy the game? Sure, some people like Maxxius just enjoy levelling different toons. That"s great. Some people do.
In EQ, *many* myself included did not, and preferred to focus on one character. In WoW, because of the fact that you can"t do shit a lot of the time with a group/raid based character, and cuz you can only have two tradeskills, you MUST have alts a lot of the time. You are almost required to have 2 or more max level characters.
How about this instead: make the game at max level a REWARDING EXPERIENCE for just your one character with no horrible defecenices because zomg my DPS sucks or because I can"t do the right tradeskills. Let everyone get every tradeskill if they have the patience. OR make them not required like they are in WoW.
Make *DAMNED SURE* that there is reason for me *and* other classes, who could solo, to want to be grouping all the time at max level and achieving things that are impossible without at least 4 people, so that I don"t feel the need to have a "better" dps class just to farm shit.
put some open-ended advancement system that actually rewards me for playing a max level character, but again, don"t make it based on solo farming shit, or once again you screw over some classes.
I"d rather just have one character. Make that an option, don"t focus on making it easier to have tons of max chars. Sure, some people will always want to twink and try a new class, and that"s great, but you should not feel obligated to because of anything other than "i want to try something new"
