Do you think it is a good idea for the devs to focus on PvP development early on? Why or why not?
Personally I think they should focus allocating all resources on PvE and refine that experience into a grand one, then release PvP in a well planned future expansion. To get the strongest foundation possible then move on to the more complex and luxurious features.
If I remember correctly City of Heroes did not have pvp at release, heck, it didn't have it for a few years after, and it was in my opinion one of the best PvE games ever made. It was the type of game that you could use to relax and wind down from after work or school, make a few new friends, and maybe order a pizza, hunker down all evening, and get lost in another world without having to worry about the metagame or other players jumping you or losing your ranking.
I would like to Arenas and Warzones in at some points, at least a /duel function for settling heated disputes and what not.
