I wonder why people expect an mmo be focused on solo content! If you don't like playing in group then this genre is not for you mates.
There are 4 different difficulties for raids and 3 different difficulties for dungeons without considering various levels of m+. Any pve player can enjoy the game to some extend.
There are multiple ranked and unranked pvp stuff in game.
There are plenty of open world stuff such as treasure hunting, collecting toys/mounts, main and side quests, reputation farming, achievements, and other stuff. If you enjoy open world content and you dont have so many achievement points (specially loremaster) then you cant whine about lack of open world/solo content.
If you dont enjoy any mentioned activities then this game is not suitable and enjoyable for you and its better to find another one.
