Like the title says, raiding nowadays is too hardcore and time consuming. Many my old guildmates have quit raiding because the effort it needs every single tier.
Last two expansions the insane farming required for artifact power grinding is outrageous AND consumable farming in top of that.
I'm fine with gearing 2 raid ready alts if there would be no AP.
The raiding scene must go back to its root where you didn't have this insane mandatory AP grinding to stay competitive. I have raided hardcore every single expansion excluding vanilla and this expansion is the first one where I seriously think going casual, and I'm not the only one.
e: my suggestion would be making actual raid bosses harder at launch of tier, don't make first 80% of bosses loot pinatas. Force guilds to smash their heads on first bosses as well, but maybe make it so bosses drop more loot so it doesn't hurt average guilds in overall progress. I'm fine with longer tiers if there would be no AP grinding every single tier.
