I hope they introduce domain locks. Not limiting one god to one domain, but "allowed unless it really doesn't make sense". Like, you know, Light or Life Cleric of Shar... quite ridiculous.
However, for that to be viable, there would need to be more domains (and more deities would hurt either). If you were to restrict the domains now, you'd only have one choice for Shar clerics, for example. And some gods wouldn't have domains that are better fits than just "Light, Life -> good, Trickery -> evil" (more or less).
