Gnomes place their loyalty in themselves, in their friends and in their inventions. A few follow a loftier path and pay their respects to the Holy Light.
how many gnomes that pay their respects to the holy light is unknown.
though, in Wrath of the Lich King the alliance perhaps need help to clean of the scourge, gnomes who mostly only helps with machines, guns and flying machines. maybe they could help even more in helping cleaning the scourge with the holy light.
although druids and shamans wouldn't really be gnomish since they both exploits the nature and sometimes destroys it (blowing things up/the gas bomb in gnomeregan)
but who knows? aslong as there are healing classes for them
Anyways, to the real topic (finally), I agree that the Gnomes should have a healing class. If all Horde races have healing classes (Even the Undead!), why do we have one race that isn't able to heal?
It's a little unfair and unbalanced in my opinion.
