This game has SO many flaws, even on standards. I didn't actually believe it (because of popularity) until I play this game. - (on official website 2017)
Grinding through the levels. DEMO: 1-20 level.
The level design IS a dangerous place.
Enemies attacking with no guards protecting in the place. Which should not be in there in the first place!
I'm nowhere safe in this zone.
No secret (items,weapons) rewarding for exploring.
It's very hard to get invested especially long ass tutorials.
PvP can be pretty unbalanced. - You have to have the right (items/armors/potions/etc..) and also hitbox are so off the limit it doesn't matter where you are.
You'll die many times. Recovers are even more struggle to wait 8 minutes.
Respawn enemies are bullshit. They are completely random. (Time & place)
Drop items are annoying. Because it will be gone in some seconds.
You can't change the class once you choose you stay that way. Remember kids: Mage doesn't heal. - except if you keep ONLY the enemies turning into a sheep and heal themselves somehow. WTF!
Doesn't scale the difficult.
It doesn't have the consistency sometimes: (Fire torches. Sometimes it hurts you, sometimes does not.)
You're wasting MY TIME! Yes, The game told me that.
Chat is too limited to talk also when you chat in long sentence, it just disappear.
No movable HUD to organize yourself. Also it's very small on bigger screen.
The most struggle of all is to how to find the friends (where are you? - also the map doesn't show anyway the players)
You cannot be on the Team both having the same quest, unless you post it on Blizzard mail, not in the game.
WOW, did not age well.
