In a nutshell, The Classic+ crowd is everyone who likes Classic but isn’t happy with it AS IS, and so they want to make changes to it. The changes that have been proposed are quite vast…a veritable laundry list of changes/features that drastically alter the game such as adding retail QoL features like the barbershop, transmog, AoE looting, multitag mobs, etc. But they also want Classic+ to replace the expansions entirely and branch off in a different direction with more Classic style content. No raising of the level cap, and more dungeons/raids. They want to have horizontal progression, not vertical. No flying, no LFG tool, no CRZ, etc.
NONE of it appeals to me in the slightest, and Blizzard isn’t likely to spend the time/effort/money developing new content for a version of their game that is 15 years old, not to mention the fact that they can’t make good content anymore to begin with, so even if they tried they would just butcher it and piss a lot of people off in the process…That and the fact that it would be splitting the focus of dev teams between that and retail, which would only hurt the game as a whole, and without plenty of people playing retail, it will die, and Classic will die right along with it
Here give this one a read…I found many of the comments by the OP to be extremely misguided, arrogant, ignorant, misinformed, and often times hilarious
