I did Eseless and other Heroic Quests with people. And all the time i see people asking Group for Heroic Quests in chat.
And i prefer to play ALONE, i don't really want to play with other people when questing. But game forcing me to play with other people when questing. But i'm not angry about it, it's MMO game anyway (/thread ?). I can skip these quests or can group with people and enjoy it. I'm choosing to play with people, because i don't want to skip anything.
In other games you can't find group if XP is low (or reward is bad), hell, i don't even know how much xp i will gain, i'm just doing for to seeing it.
WoW completely left group quests. Now all classes can solo all group quests. If u ask it in chat, they will say it to you "Lol, i just soloed it noob!"
If you want to see people, wait for everyone reach to 50, u will see more people. If you are high level, i have a news for you, some people have life, jobs, wife, children etc. and can't play 10-12 hours a day.
