Let's begin with when playing in a group, the missions are not shared. Everyone needs to talk to the same people and kill the same things... Meaning if you are in a mission with a group and you die right before killing the boss, you are f*ckd and won't get to complete the mission.
For missions, I wish there was better guidance in the game, the missions are just all over without any meaningful guidance for the character level and sometimes you don't know how to get to the location exactly, poorly developed. Also, the UI screens and chats are not well developed either, sometimes you get stuck in loops clicking, just horrible.
The runes are literally impossible to find which make very annoying, and no guidance at all really where to find it... in the first mission for runecrafting almost impossible to complete, very poorly developed.
The maps needs to allow better zoom, it's very difficult to see the small destination locations in a barely zoomable map...
Do yourself a favor and go play Neverwinter, you will have A LOT MORE FUN!
