"Fear not, armchair general! There's a new strategy guide out there called the WARbander's Handbook that just might help your smaller force take on the zerg in Warhammer Online!
"Zerg" is probably one of the more common words that come up when you talk about large-scale PvP in MMOs. Other words synonymous with "zerg" are "swarm," "overkill," "mindless," "%#@#$!" and "what a bunch of lamers." Okay, the last two were expressions, but they're probably the most accurate."
