What you need to do is use reverse physiology. Next time you pitch a campaign, say that everything is fine except X,Y, or Z. Naturally, all your players will want to play X, Y, or Z! Of course, you campaign is actually set for X, Y, Z to be the focus of the campaign.
This is a major reason why I play so many dragonborn. It ain't optimization, and it ain't because they're better at being fantasy Kklingons than dwarves or half-orcs.
