1) Gnomes feel inadequate.
2) Numbers are, apparently, worthless
3) All pro-iksar, real-world applications (Iksar FD+Lich vs Others FD+Lich) are dismissed and replaced with "But gnomes look through walls" or "30int is better for burst fights."
Anyone who tells you "regen doesn't matter" is misinforming you and has either never played a Necro or plays one poorly.
The only reason to not play Iksar is that you don't want to be an Iksar, which is fine. But at the end of the day we're all just spooky skeletons, trading Hp for Mana into DoTs, one tick at a time.
