I'm not sure how many of you played the game. Missions were difficult to achieve success and let's not even talk about the bonus part. Missions in GW1 were about achieving a goal as a group - killing a boss, rescuing someone, retrieving something, etc - that required different skills than the regular game. There was a high chance of failure. You had to change individual builds and gear and party synergy to for different missions. The issue is every mission was instanced. I don't know if Project Gorgon's game engine could even do this.
Eric, if you are watching, can you please add something like this? If it's even possible, of course.
