I like the monk changes. GL4 is awesome, anatman and full aoe rotation are handy. Howling fist is gone but replaced by fancier howling fist that is usable more often in aoe situations (I know people are upset at losing the free potency it gave since now it's shared with Forbidden Chakra, but that potency will be made up elsewhere). I see a lot of people grumpy of six sided star (oy vey!) but it's a situational move and not one you'll be spamming, so the long gcd is not an issue in my opinion.

I never had an issue with riddle of fire's slowdown, really you should get used to it after doing it so often and now it'll be a bit faster in GL4. Tornado kick is still there, meh, but it'll find it's uses I'm sure.

After monk staying mostly the same since 2.0 aside from gaining OGCDs and losing dots, I'm interested to see how GL4 will change the flow of our base combo. You may be able get away with delaying demolish to every 4th and twin snakes to every 3rd, keeping dragon kick every 2nd for the bootshine buff, assuming they don't change durations.
