Why? It de-humanized loot, you chase item level upgrades of the same item. In fact, most of the time you don’t care about the name/etc, you just import pawn strings and sim. That’s an arpg, not a rpg mmo.
Classic wow has reminded us that tier matters. Loot names matter. You remember getting dying curse or jet’ze’s bell dropping. Since M+ was added, does anyone actually even read the name of the piece that dropped? Outside of a few instances, nope. Just chasing ilevel.
It’s straight up a loot grind. No story-telling, no content, just affixes and more health/damage.
Adding H+ to classic is the canary down the coal mine. Buffed health/damage, with an affix. It’s a simple M+, just 1 difficulty level.
You can definitely see in WoW’s history when the D3 designers came in.
To repeat myself, M+ design is an ARPG. Specifically designed to provide content with relatively little added development/design work.
I’ll go further, adding M+ as a 3rd pillar of end game progression broke WoW, and is now effectively stopping people from coming back/staying. It’s a boring treadmill that you have to do in order to raid. And adds significant additional time commitments.
Most players don’t have 30+ hours/week to play.
Back to wotlk. Take the average casual player. Heroic+ HoS is taking pugs 45 minutes, possibly even an hour. A number of groups didn’t finish it!
H+/week: 7-10 hours (1 hour/dungeon, 30 mins+ to find a group)
Raiding/week: 7-9 hours
Dailies/AH/etc: 4 hours (say 30 mins/day)
That’s 20-23 hours/week for your main character. Add an alt, now you are at 40-50 hours /week. (and people loved wotlk for it’s alt-friendliness, which H+ is going to kill).
In OG wotlk a daily dungeon was 15 minutes, and you could sit in queue with the RFD while doing your dailies. So now you are at 10-15 hours/week/toon total. 25%-50% reduction in time/character.
(btw can’t do your dailies while pugging H+ right now, all the tanks are gone. Tanks have disappeared with Phase 2. So you have to form, spam LFG/trade/guild/discord, etc).
Plus, I can confidently say that almost no one is running H+ right now, and there is significant community dislike. Despite it being an incredibly fast way to grind conquest badges (5/run, 35/week). And yet no one is doing it.
Blizzard has the data and know that H+ so far is not seeing the expected engagement.
Classic should be building the game that the players want, and loved back in the day. Which isn’t retail.
