Not really inclined to stay playing this game if this is how it goes...

As Legion88 said, use Party finder with message that you have bonus and do it unsynced. You will have party in no time. And as he also said, this will not put you to 51+ areas. More then 100 quests will follow after this before you can touch HW. No joke. I almost quit because of it myself (when I was in your position, there was no option to do it unsynced and I had to wait for days to finish some of them, at least this is easier now). But anyway it was really a dick move from SE to gate access to HW behind this and I am sure it costs them quite a few players. There should be an option to get to HW without this.

EDIT: It is nice from SE that they are creating new MSQ quests for players that are already in the game, but it does not really work with player who start to play now and is trying to catch up with their friends.
