That's not the ONLY problem Cobra. After playing Champions Online for a while, and then trying to go back to CoX, I just can't do it. The graphics aren't what kills me. The combat is just too boring (though some ATs are better than others), and the some of the instances get mega repetitive - caves and office buildings in particular. I think CO has a better balance of instanced missions to open world ones.
Also the player created content (mission architect) hurt availability of teams outside of AE facilities. The worst part is that for every awesome player-made series of missions (like Footsteps Initiative), there was about 50 others that were terribad - not even counting supermegaleveling farming missions.
Don't get me wrong, there are a lot of good things about CoX, and it was a great game back in the day. I still miss masterminds, they were by far my favorite, even more than scrappers. But I just can't go back to it. I can tolerate a little Champions now and then, especially after all the improvements they have made. I'd like a superhero MMO that leverages the best of both of those games, really.
