Made a post on a different thread i wanted to expand on a little and share with general (no TLDR tried to bolden some points, sorry!)
What makes WoW less enjoyable now imo, as someone who is heavily invested into the game (it’s where my free time goes). Edit: I did take some parts out of this post. IT was a response to m+, don’t think m+ is an issue outside of balancing. Most of the players that complain about it, IN MY OPINION are one of the contributing factors why the game is trash, bad feedback and whining, you don’t need to push high keys, you can easily do a ten and get in time if you’re not complete trash. we get it some people said some very mean things. Mute them and move on. I stand by my point for M+. It’s a good thing imo which is why it’s not included in this post.
Convenience (not flying, that didn’t ruin it, maybe how flying doesn’t interact with the game like it did in tbc or wrath makes it kind of meh) group finder (LFG).
We don’t need 4 difficulty modes. Remove LFR, remove normal. 2 modes normal (the current “heroic”) and mythic for raiding content. Again my opinion and everyone has one. Some people’s opinions are a little more valid than others though. 
Make loot matter. Dungeon loot should matter before a new tier, not M+ but mythic 0 gear. When a new tier releases pre raid gear should feel more meaningful. With that said bring back the master loot system. The average player doesn’t understand the importance of gear distribution in a guild (sorry, guilds matter, community matters it’s what makes the game thrive).
Loot catch up systems do serve a purpose but if classic taught us anything the journey should matter. Make gear feel relevant and the journey that comes with it.
Bloated numbers. We get stat squishes. That’s great and all. But I think they need to tone it down quite substantially. I use to be against the stat squish when it was first proposed. But after going through a few, it doesn’t matter. You will feel as if you’re power has grown as long as the tuning is done correctly.
Feedback. Feedback is great but they don’t need to try to appease every single damn player in the game. Sift through the good feedback from the bad feedback, most of the time the majority of players in general are wrong. You’ve tried to make the game for everyone and now this is where we are. I’m not even say listen to me. Make content that makes sense for an MMORPG, if those ideas were “outdated” classic wouldn’t of been such a huge success. You literally don’t have to try and develop some new formula you literally have a formula from 20 years ago. It works use it. Develop how the specs play and obviously the new expansion but stop trying to make the game feel like a chore. Reality: most people don’t want to play your game, even the players who you are trying to mostly cater to because nothing matter and you’re trying to force players to grind out something not fun.
If you want to “open” up raiding to a broader range of players make the raid content simple but unforgiving. Honestly I think the raiding content is great, even now. I don’t think anything here needs to change too much outside of how loot is distributed, making loot important from that content, and reducing the amount of difficulties.
No more of this ap grind crap. No one wants to feel forced to do a chore that isn’t fun. If you design a good game with a good system players will want to organically play.
The game is not fun, i want to level a second mage for example. I leveled up to like 5 and already want to buy a level boost. A game that you pay for monthly and on top of that a new expansion shouldn’t make you feel like that. Ultimately my decision was not to level that new toon and play another toon at cap already. I wanted to speak out about this because… seriously the leveling journey feels like trash. And i shouldn’t have to buy a level 110 boost for 60 bucks.
Stop with the rng bs in the game. I don’t know how many times many players, which i agree with don’t like rng. They need to stop trying to “hook” players through a casino that holds little to no value. As time goes by the cache we get at reset is completely irrelevant, you’re most likely not going to get an upgrade and it just feels so bad. I don’t feel excited about a cache that will probably not result in an upgrade any longer. I don’t know the last time i received something from that cache that was worthwhile.
