Rogues

According to blizzard:

Rogues are a lightly armored melee class capable of dealing massive damage to their enemies in a flurry of attacks.

According to Jemsy:

Rogues are best when they are short, cute and named Jemsy!

We attack the lower ankles of the baddies with vicious speed and fury, crying; Gnomes for the win!!!
Noone shall escape the wrath of the ninja gnome!
We never turn down a chance for some good plonking.
No retreat, no surrender (unless we feel like it).
We sometimes attract alot of threat and thereby make the healers heal us and use up all their mana. This is because we want the healers to feel useful and to keep the attention were it belongs. On Jemsy.

And if something fails and the raid wipes, just blame Ratty, everyone else does.
After all, we are much, much to cute for anyone to blame us for it.

Your humble servant,

Lady Jemsy Vader, queen of the ninja gnomes
