Some others that come to mind:
"Wow has an extensive cash shop"...no, it doesn't. There's literally like 20 things in total and they are all cosmetics.
"It is an objective truth that X expansion/dungeon/raid/zone is good and that Y expansion/dungeon/raid/zone is bad" - no comment
"Classic wow was immensly successful so therefore this and that thing should happen to the proper game" - people living in a dream, classic wow has been dead since 3 months after its release, nothing at all as far as design decisions should be implemented into real WoW from it
"It's much better when you are just an insignificant adventurer in a game rather than the chosen one / hero / messiah" - yeah, there being no story and you being an unimportant person makes for a great story, try again
"Mythic+ ruined raiding because it gives infinite amount of loot! No point i raiding anymore wooo!" - raiding is still factually the fastest and most optimal way of gearing up, gearing through m+ takes ages and the fact that you can "spam" them doesn't matter
"X pre-legion expansion was great for a casual player" (Bonus points for: "WoW Classic is great for a casual player") - before Legion there was about 10 times less world content and random casual things you can do, wow classic has literally nothing to do besides leveling
They aren't. Though in hindsight I can see how someone can think I meant the first one in the sense of attacking people for not clearing higher difficulty. Maybe I didn't phrase it in the most clear way. Heroic is what relatively hardcore players do, that's why I mentioned the difficulty. This is the main accolade for a regular player as far as pve goes, so by someone who just clears heroic I basically mean a person who just does the raids and dungeons and skips the other content completely
By no means do I meant that the highest difficulty doable by regular players is too low, or anything like that.
If you feel they are easier that's your right to have that opinion, but it's almost objectively untrue. If you compare the raids from modern expansions directly against the older ones it's clear the newer ones are much more complex and challenging
