I would. But in Magic I'm a Johnny. In wargames I like to build warbands that are 'cool.'
One of my players would never be bored, as long as he 'wins.' In Magic he's a spike. In wargames he builds the 'best' army. He likes to win more than he likes variety and flavorful choices.
To each our own, but a good system should allow us to play reasonably well together. The power gap between his PCs and other PCs has always been tight enough for me to challenge everyone in every system we ever played (including non-D&D games), except the last two years we played 3E.
I'm not sure I'm down with Timmy, Johnny, and Spike analysis for D&D. I get what you're saying, though. What I'm not sure of, is whether its possible for Spike to get his "I'm better than anyone else here" fix while having the rules keep Timmy/Johnny in the game despite their comparative ineptitude. At least, without creating a system of profound inter-class dependence or mandated mediocrity. (I want better names...these names will invoke too much inadvertent allusion to MtG, I fear.)
Really, though, the more these discussions go on, the more I wonder if they aren't solely creations of the internet as a medium. I played and ran the game for years with parties of characters that were obviously of unequal relative power, yet it never seemed to utterly destroy my games as many on here seem to feel LFQW inevitably does. Thinking on it now, it seems to me that among the various groups I've played with since 3e came out there is a distinct positive correlation between the time they spend online discussing D&D and their awareness/experience of the commonly cited problems for older editions. Whether that's an effect of CharOp, discussion, predisposition, or something else...I dunno.
