Not sure why they waited all this time to tell us they were taking the cloak quest out. It would be pretty tight to get it all done on time before the expansion. The major holdup would be the 3K valor requirement that is going away in 6.0.2.You have time. Start it. Even with shitty luck, you can get everything pretty quickly now with bosses having mandatory drop of wish/stone/relic blah blah blah. Itll be far more beneficial to you than you think.
