If Blizz has no intention of maintaining old raids and dungeons then yes people want it soloable. That’s pretty obvious. You are addressing things like everyone’s opinion on this is rigged when it’s very obviously not. It’s hard to get groups together for this older content due to there being no incentive to do it. Either add the incentive or make it soloable.
If Blizz wants to revamp old dungeons and raids. That is obviously welcomed but it obviously requires way more work to do. No one is complaining that they are using old dungeons for M+. Same with revamping content like the Mage Arena. Unless you dig the bottom of the barrel for complaints to prop up as the supposed common opinion.
I’ll never understand why people on the forums are so condescending towards stuff like this. Especially when it would benefit everyone either way.
