More Critical % just means you'll have a better chance at a "critical hit" (more damage) everytime you hit your enemies! Currently at lvl 21 I would say there are 3 Weapons that are very useful to us Warriors. Artic Ward of Will (sword & shield for armor), Might Vorpal Sword of Assault (for it's Dmg and 100% Crit Buff) and Pit Sword of Potency (also for it's Dmg and burn proc).
