As for advantages, evils have ap's and necros with sleep, if its a crowded room you can sleep, blind and such. Making fleeing safer. You dont have that much healing at hand, with the exception of a necro having his zombies there, and his vamp touch. So I would not aggrea that ranking as evil is that much harder than ranking as a goodie.

But I do aggrea on that you have less places to go ranking as a hero... But I see this also as a reflection upon that there are only two good only races. and 4 evil only races. And that there are 3 evil only classes(including orc here) and one goodie class...

Just my view of things....
(and yes I aggrea that a paladin is a great tank with sanc and heal)
