Boomtown has published a short Q&A with Cryptic Studios' Jack Emmert, quizzing the creative director about a few pending issues with City of Villains. A snippet:
Q: The new archetype, Stalkers, have a hugely powerful (and thus controversial) attack with Assassin's Strike. Are you happy with the way it works or will it be changed?
A: We might be instituting a system where players can't be "one shotted", but that wouldn't be particular to any Archetype. The Assassin's Strike is in fact just one power among many that leads to one shots in PvP.
