I don't envy anyone who has yet to get keystone master. Between the nerfs to some strategies and current rotation of affixes, it might take a month or more before an easy affix week arrives yet again and you can push for keys with pug groups.(In case anyone is wondering: this week is bolstering, next week is spiteful and grievous, second next week is inspiring and necrotic, and the third next week is sanguine. An absolute pain for any healer.)
There something to say for the list of dungeons, but I do feel there seems to be a bit of high RIO bias. To put that into perspective: it seems to deal with timing 20+, rather than the overall difficulty on a 15. It depends on what you want from +, but the majority will be more focused on the latter than the former. As a KSM (3M CN) that timed all 15s on Tyrannical weeks, I base difficulty on the tendency to wipe on singular mistakes, as is expected from groups that don't play the dungeons day in day out and want to be 'done' with +s. With that assessment, I put ToP, Spires and Wake a lot higher as you have control in these dungeons and lenient timers. Mists a lot lower, as both Mistcaller and Tre'dova are key killers. Depths and DOS are pretty much always the worst dungeons; terrible timers, no wipe leniency, limited space and horrid bosses.
Your placement of halls is laughable, its not always a top 3 dungeon, the timer is short af that it requires a skip, bolstering affix makes this super slow and with packs moving you have to be extra careful otherwise u pull more and have to deal with more bolstering or u die to reset either way losing time and not to mention the bosses still have a lot of health and its easy to wipe on the first two, you basically need to make no mistakes and have a venthyr to even barely make the timer
Its fine if you play with the same people, but pugging is an absolute nightmare. Everyone picks the highest IO and/or Highest ivl MDI class. I go the route of highest IO, how many timed 15+ theyve done, which bit me in the ass multiple times. I swear half these orange players been carried through with the twitch streamers. How can you possibly time over 50 -15s and not know simple mechanics or your class defensives,. Many times ive had hunters not trapping, not interrupting, not turtle'n, standing in bad, etc.. its mainly hunters but others also, all these dps do is dps, nothing more, I'd rather take a warrior because you know he has nothing as defensive and all he is good for is dps - zero expectation otherwise.With that being said: Tyrannical should be out of the game, why make boss's into raid boss's and as someone said not only we have Tyrannical, we also basically have fortified every week or some form of 'slow down' affix or grievous. Blizzard needs to rethink and redo M+, a whole new set of affixes. They also need to do something about gun and run tanks, many classes (ele, mages, hunters, etc..) have an aoe that you put on the ground and in pugs, its useless because the tanks move so much.
