i have 4 pc t21, i wear 2 pieces in my dps set just because the stats are actually pretty good. If i have to tank anything that hits remotely hard i swap to T20. I think i am the lowest ilevel in the raid in my tank set, between wearing 4pc T20 that is ~935, and my weapon having 2x 910 relics and 1x 930 im only around 940 tanked out. meanwhile im 953 in my dps gear..yep i drop 13 ilevels so i can tank things; thanks blizz.
the fix to felhounds was good, tanks now get opposite buffs and there are gaps where swapping makes sense, that fight is just a pain in the ass for monks, i take a ~4 million magic damage after stagger (close to 50% of my hp) every 10 seconds, and usually have a dot that is doing 2mill every 1.5 seconds. then you have incidental damage like having to stack for fears and if some jackass misplaces fire puddles the tank just has to stand in them and eat it up.
Method 3 healing the end boss is pretty funny, i was watching the Korean/Chinese guilds stream their progression and it didn't look like a lot of raid damage was going out but it did look like tanks were getting rocked. I'm glad this tier is "easier" than Tomb nobody wants to bang their heads against shitty shitty wall mechanics. the fights in ABT are strong so far, but dont feel like they rng fuck you nearly as bad. we'll get our first pull on Imoner tonight (im missing due to seeing Star Wars) but im guessing he's easier than he looked the first week of mythic just due to the gear levels floating around at the moment.
