MAGE – Mages take advantage of Gnome racial abilities. Expansive Mind increases mana and intelligence gained by equipment. Engineering is a useful skill for Mages and the specialization makes it easier to increase. Goblin Jumper Cables give Mages the ability to resurrect other players, and can only be used by Engineers. Arcane Resistance reduces the chance to be silenced and is an important passive.
ROGUE – Engineering is effective for Rogues and increases their versatility dramatically, especially in player versus player. Expansive Mind has no practical effects on Rogues. Arcane Resistance decreases the chance to be Polymorphed, making it a powerful racial for Rogues. Escape Artist is the most useful racial ability for Rogues. Movement impairing effects are the bane of Rogues and the ability to instantly remove them make Gnome Rogues formidable.
WARLOCK – Expansive Mind is doubly potent for Warlocks. Intelligence increases the mana of both the Warlock and their summoned demon. Arcane Resistance is potent for hindering both Silence and Polymorph effects. Engineering isn’t useful for Warlocks beyond the universal benefits. Escape Artist is very situational, used primarily when fleeing.
WARRIOR – Escape Artist allows Warriors to keep proximity with targets. This is a necessity for Warriors and should be used often. Arcane Resistance fortifies Warriors against Polymorph, a Warriors bane. Expansive Mind helps with leveling tradeskills only. Engineering is a powerful skill for Warriors, increasing their effectiveness in all situations.
