A smart weaver is a very deadly thing to fight. One thing I would like to add is how to fight against catch prey, and there are around two ways to go about it.
One: you can either try to always time your attacks so they hit his backside so they land to avoid there high block/parry/evade (attacking from behind means he can only evade your attacks)
Two: this method is very tricky because it takes good timing to do. You can knock off catch prey buff off the spider itself IF THE SPIDER IS CC when catch prey refreshes itself every 5 seconds that means either routing cry stun or a lucky chance on battle-shout fear (with the relics that give battle-shout fear proc from the moors)
Good Luck
