You can enable warmode. They are combining PvP and PvE realms, this is really just another squish (like dungeon qing 15-60, to combat low population numbers). The system is fantastic though, from what I've seen. I like having the option. You'll get 2 PvP talents at 70 I think... You can fight everything without hit issues, you just don't scale. Meaning your attack that hits for 1k hits the 120 for 1k as well, its not a % of their health. If you had amazing kiting you might do some damage but they can oneshot you and have like 70k health.
