Iksar necro XP penalty

[mjrau]

I was reading on P99 wiki that Iksar necros used to level slower than the other races and was wondering, even though it probably wont make much difference in the earlier game, how much does it effect later game levelling? i used to play DE in the good ol' days and was gonna try the same this time but have been dabbling with an iskar. so my question is...is the health regen worth the xp penalty?
