Having to constantly group up in dungeons just to play the Main Story is NOT why I play MMOs
The key is in the word(s), MMO. Massively-Multiplayer-Online.

I braved the dungeons to get to 50 but hated them, people were often rude and critical and I couldn't understand why SE wanted to force me to play this way, it is so contrived and predictable. I feel as though I am being forced to play their way
It may be an old thread but let's make something clear - just because someone has an issue with how (some, not all) people conduct themselves in a Dungeon, this doth not maketh "Dungeon(s)" the problem. As for 'being forced to play their way', see above - it's an MMORPG. If people walk into an MMORPG expecting to wing it solo like a SP-RPG then they are setting themselves up for disappointment.
