We had to make a change to the new warlock summoning mechanic at the last second to prevent an exploit. Our apologies to all the law-abiding warlocks who have to suffer with a painful cooldown on your summon in order to fix this problem. We plan on getting the Ritual working correctly as soon as possible. You won't have to put up with a 2 minute cooldown for more than a few days. Standard caveats apply that this could change for any number of reasons, but we wanted to keep you informed of our plans at this time.
What ever happen to the few days
