How do you handle the disproportionality between 'greater' beings in terms of classes?
Obviously, they aren't meant to be played per se, but they often have higher level creatures which advancement listed as 'By character class' and the like, which doesn't jive well.
Example: A cloud giant is a 17 HD monster described as potentially entering the cleric class... But what fucking good are half the cleric spells in the context of a 17 HD creature? Whats the value of a +1 to-hit (bless) or 1d8+1 hit points (CLW)?
I know there are a few examples of ways to handle it (for example, specific prestige classes, as was done with the dragons in Draconomicon to some degree), but I'm curious to hear how others handle these scenarios.
