Opinion:
The plight of LFR allowing everyone to tour-mode through raids has bred a pretty overwhelming rush mentality of ultra high expectations.
Do away with LFR, you increase the value and allure of raids through curious mysticism and the want for the good gear and mogs. As a side effect you boost community efforts in-game. In-Game being the key element here. Everyone uses third party programs for real communication but with people relying on guilds, pug guilds and local community you boost the reliance for community.
Yes, I get the solo aspect completely but even as mostly a solo player I myself, not even others I know actually expect to be able to acquire top-tier stats without partaking in content meant for large communities that rely on good communication.
These are key life skills that a lot of gamers don’t get out in the real world during their budding years and even less so the past year. WoW taught me strong communication skills and how other people are very different and still very cool back when I was a naïve 14 year old with no real friends and a hellish school life.
Do away with LFR, you help do away with ultra high expectations from the playerbase. I’m mostly referring to people expecting good loot drops every boss. Easy fights so they don’t have to concentrate. Other people to carry them quickly so they can glide through the story, not paying attention anyway all because they want the loot.
There’s so much more you could do with the open world outside of raiding to supplement the lack of LFR such as having rare elites that have a small chance to drop something really good like a trinket with interesting mechanics like letting you instant cast everything for 3 seconds on a 5min CD. But make that loot drop random on any NPC with a low chance so hundreds of players aren’t just spawn camping it for hours. Have it like time-lost. Random spawn location, long times, triggered by the deaths of other rare spawns.
That’s just an example anyway. There’s tonnes more that could be happening for the end-game era outside of raids.
Make raids valuable once again, cut out the difficulty levels and just have a scaling thing depending on the number of players so everyone deals with the same difficulty level. 10-man raid? still tough but smaller health pools and less loot. 40-man? chances of elite stuff, harder because bigger health pools but same mechanics. Atleast in this regard, everyone who does the raid also gets to see the bonus mythic story elements and mechanics.
There’s really no need for LFR or difficulty levels, you’re just creating way more work for yourselves.
