Cooldown, in comparison to previous iterations of LoD Rat, is absolutely not needed anymore.

Our offensive priorities are: Skeletal Mage Damage > Critical Hit Damage > Physical Damage > Critical Hit Chance > Attack Speed > Area Damage > Cooldown Reduction (CDR). The guide at hand is a resource for you to succeed with your ratting! When Rats go well, they feel amazing, but when things go wrong it's one of the worst experiences you'll witness in any group setup. Therefore, playing Rat DPS requires a decent amount of practice, dedication and the patience of an angel if your zNec is playing suboptimally. The gameplay of a Rat is 'High Risk, High Reward' as it’s purely offensive and dies to anything that hits it. While the main multiplier shifted from Bones of Rathma (6 ) Bonus to Legacy of Dreams the name 'Rat' still persisted to depict this specific team composition for grinding experience (and gear for Necromancers). Initially 'Rats' were played with Bones of Rathma, which is where its name originates from as people were too lazy to search for a '+1 Rathma' and simply referred to it as a '+1 Rat'. Season after season it has proven itself to be among the top tier in experience farming.
