ok so my only gripe so far about the game is that town portals timeout after a while. I went afk, and came back and it had closed...
I see no reason for this to be a mechanic. At least we have Waypoints, but even then I had to walk and fight across a big zone to get to where I was...
Its a server issue, but also a mechanic thing. For example, you get 6 portals when you use a map. Its single use. And if you want to grab loot, you have to burst a use. And its 6 portals for the entire team. So if you want to go with 4 people, then its 4 portal used. If you die, you use one more portal too.
You have to be carefull and see what you want to grab.
