I'm new to the game and I have been trying to figure out what AT I want to be. As I was going through all the info on the forums I ended liking the spider AT's. Then I found out I have to have a 50 villian to even make one. If I'm looking to lvl to 50 as fast as possible what would be the best AT and should I solo or grp? I prefer to solo but would grp if it's slot faster. Also does raising mission difficulty make you lvl faster or does it slow you down more then give you extra exp?
