Since the board ate most of Nep's really *biting* responses
on this topic, I thought I'd offer this brief FAQ for future
searchers.

Why don't Storm Giants have vulnerabilities?

Due to the way the race has been balanced, we do not feel
they need a 'racial vuln' at this time.

But why just Storm Giants (and humans of course)?

Some guy did that a while back. It works really well so
we just let it be.

But then why do you keep adding vulns to new races?

We already have a couple races with no vulns, a couple with
varying metal vulns and a bunch with elemental/holy/poison/
disease/etc vulns. It's a real wild hair up someone's rear
that gets a new race put in and, quite frankly, someone who
is that motivated wants to make their new race interesting.
A lack of vulns is just too boring for these visionaries.

Shouldn't you go back and 'even it out' with a vuln?

We just don't see fixing something that isn't broken worth all
the wailing and gnashing of teeth that will inevitably result.
You may have noticed that in the last year the vulns of the
other vuln-having races are significantly less exploitable
than they were before.

What about removing some of the other vulns then?

Everything, including vulns, is rebalanced from time to time.
For example, Duergars lost their drowning vuln. And items in
the game are always being rebalanced in regards to exploiting
the other racial vulns. Hydrophobia is far less a drawback
than the finality of never going underwater. It's a process.

I still think it's unfair that Storm Giants have no vuln.

If that's the biggest injustice you have to face today, you're
having a pretty darn good day.
