Like the title said, i just bought the game! and i am looking forward to some fun with CoH. I like to pvp. But I dont know where to start with this game. I have very minimal experience with Super Hero games. I played Champions online for about a 3 days. and i use to play DCUO for about 2 months. I am not sure how archetype works, not sure what powersets are there. Could you guys give me some advice to which powerset is easy to use and does pretty good in pvp. please and thx.
