Incase anyone didnt know, dont bother using inhibitors on WKR it just blocks your pet from using any ws.
Since it is waiting for a chance to skill chain, and everyone and their mom is ws'ing non stop, your pet will never ws since it can never close a ws.
It waits 3 seconds from the time someone WS'es then it tries to, but it someone else ws'es in that 3 sec it will wait 3 more... over and over.
