Dev07 is very good. Not saying you can't beat him but he will definatly give you more of a challenge then you've had in awhile. Watching you beat on my wife (lol) I noticed you've gotten a lot better and even so he will be a challenge
Everyone has classes they're good at and classes they're bad at, I SUCK as Zeus really bad, Poseidon still my best class but only because I can combo, I'm a pretty good Hades Healer but I can't fight as well (I have completely random tactics), anyone can be good with Ares so I don't count him.....as for Livestream, all i know is they will show some DLC, no clue what it is, but the 4th weapon is the most likely assumption.....
I love Leia, especially the way she extends my staff
