I suppose I'd just be sad if it somehow went unnoticed, and a player thought, "Oh man! I should have got this earlier!" That can be solved by just speaking up.
I agree it's weird for someone to instantly get 9th Level Cleric Spells, but then, it would be fun to justify in the plot. Also, I did mention a "catch up," mechanism where they would at least gain levels as fast as someone else.
We don't need to compare a Paladin to a Paladin that are both in the same game. If I were a player, though, I would certainly compare who I am with what I "could be." This would bother me personally, as a player, if I didn't notice it. Maybe I'm the only one with that OCD, but, as a player, I'd be sad I couldn't hit the "reset," button on my character... but then, I have min/max tendencies :P
And, there's still the issue of a Half-Elven Bard not being as good at magic as a Human Bard could be... which seem unintentional.
I think I'll just house-rule my way around this one if it comes up, no big deal.
