Edit: 9-15-20: Thank you for your reconsideration of the necrotic affix.
I understand that you guys are trying to close the time gap between fortified and tyrannical. In that aspect you have largely succeeded. Tyrannical has felt more reasonable than ever. At my level of keys it was always playable and tough but fair. And at my ratio of pugs to premade runs (very pug frequent) tyran mostly just punished groups with underperforming dps.
Necrotic is already brutal in its current state. Learning of the necrotic revert on PTR was some of the most devastating news I’ve seen in a while. While it may have been misinterpreted via data mining in the first place, cutting the rate of stacks for all mobs would have been a great change. My greatest fears have been confirmed, and fortified necrotic now exists in the game. This season is more accessible than ever for those coming to mythic plus keystone master has been easier to get than it’s ever been. Necrotic, however is an immense outlier, and now that it’s paired with fortified this is compounded greatly.
With the routes that I’ve followed to this point in the season, and what the best players normally pull, I’m trying to picture this affix if the interpreted 50% nerf to all mobs had gone live. It would still be quite prohibitive without good play, and still by far the most difficult affix.
In it’s current state, yes I can time 15s on the 5/6 tank classes that I play. However, logging onto one of my dps for a max vault will be an unecessairly long wait for a tank. An overwhelming amount of the time in group finder this long wait is for a tank that shows the affix no respect, dies instantly and leaves or compels other players to leave and ruin the key after a 20-40 minute wait.
This week and most necrotic weeks the average Joe is deciding what they can sacrifice on their M+ progression path for the week. The majority player opinions I regularly read are usually to the tune of getting much lower, much less of or no mythic plus great vault at all on necrotic weeks.
The ability to solo carry this affix varies greatly across all tanks. Paladin and UFR Bear feel quite good. Warrior is dependent on the pull and what’s hitting you. Demon hunter was the king of getting threat and running for their lives in 2 globals all of 9.0 regardless of the affix. Brewmaster being all but immune to boss necrotic is pretty cool, and ring of peace. Blood death knights have excellent tools to deal with dropping necrotic stacks, but their effective health drops faster than any other tank per stack. They also lose threat extremely fast without uptime damaging the mobs, even with mediocre DPS players.
I’m not even sure what it is I’m asking for here, and this is going off topic. You guys are really on a roll with quality of life and accessibility changes though. 9.1.5 looks like even more reason to play the game than ever before. Mythic plus has been a huge part of my life, I literally can’t enjoy this game any other way my life doesn’t allow it. It feels like a chunk of the group finder dies whenever this affix comes around, and I’m hopeful you guys can give it another look.
