To note for me casual players are more than just LFR players moreover when you can easily raid log on classic if that’s all you want to do. LFR is more for players that don’t want to play with a guild and are more solo players and while sure there are other goals like people trying out stuff in it it’s something you can do in normal too. I don’t really feel this is a casual vs hardcore problem but people not wanting to play with guilds or not being able to.
Considering the addition of H+/Celestial I’m not sure how LFR would work and while I’m not opposed directly to it I don’t think the experience would be as good as people think it would be when more geared players have no reason to go there for loot it and when it hits the same problem as originally in mop where finding groups gets harder and harder throught the week which makes queues very long.
I still think the choice in term of vision could make sense but considering the lack of integrity when it comes to rmt/botting which have been left rampant and the existence of the wowtoken which is rmt but done by Blizzard I’m not sure there’s a leg to stand on in term of vision when those damage it a lot when at least in my opinion classic players value integrity a lot more when it comes to what they think is “classic”. Moreover when it feels like they have given up on taking care of realms when it comes to mergers or straight up with fresh servers in Wotlk when they provided free transfers before even letting people transfer in which feels like a sabotage.
