10 years ago there were so many things in this game that got me excited. Downing a boss for the first time, getting a BIS piece of gear, or a weapon upgrade, finishing a long grind with a cool reward ect.
It feels to me like over the past decade blizzard has tried to increase the frequency of those feel good achievement moments to the point that they no longer feel like achievements.
Right now killing a boss does not feel like much of an achievment, because most average guilds down a boss every week or 2 or so for the length of the patch. When you do get the kills there much less rewarding because you never feel like you mastered a fight, Just either out geared it, or didn’t fail it badly enough to wipe. This is partly because most bosses today have a gazillion mechanics, that all deal moderate to light damage should you fail them. This is because to do fights like this perfectly would require world first raiders with weeks of practice on a fight. So instead of having a few simple mechanics one can master to kill a boss, you have modern fights with tons of mechanics, where you only need to reduce the fail damage to the point your healers can keep you up across the fight. Killing a boss when most players in your guild got hit by 2 or 3 different mechanics does not feel as good.
Gear comes so quickly now at the start of a patch it doesn’t feel very rewarding, and when you do get those few upgrades later in the patch there often war forges, or gems upgrades which again don’t feel great.
I honestly think the last thing i got excited about in wow, was when a legendary dropped in legion. For me that is quite sad.
I am aware if your in an average mythic guild that raids 3 or 4 nights a week, you can still get this sense of achievment. just it used to be available to lower level raiders as well.
