To make the game better, i think that there should be a mini-map on on one corner of your screen. Sometimes you can get lost trying to find the story line quests so i think there should be little quests icon on your maps to notify you where there are side quests or story quests, and just to make a little more exciting there could be little dots marking where your friends are at.
There should be another mount that can take more than one person, like a motorcycle with a sidecar.
Just turn on the quest helper, it will point you in the right direction. I try not to use it, maybe I'm just cocky like that, but it's still there, and that doesn't mean you can't.
