So my friend and I have been playing together and we've been grouped the entire time, we're level 6 now. The quests have all been solo and there hasn't been a point in even being in a group the entire time other than seeing the arrow to know where we're at. So I figured once we started getting to the quests where we're in instances, away from other players, we'd be doing the quests together. But that isn't the case? We recently started the fighters guild stuff and one of the quests is to kill dophia or delphia or whatever her name was, which is in a little dungeon like area away from other players. My friend and I are grouped, but we can't do the quest together. It just shows an arrow like he's in the same quest room but he's invisible. Is it a solo instance so we have to do it by ourselves? Are all the quests that aren't public with everyone running around like this? I honestly can't tell if we're bugged or doing something wrong or not because every other mmorpg i've ever played has let groups do the same instances together. Just wanna know what the deal is.

Youre in different phases. One has to join the other's phase.

Can someone tell me how to do that please?
