They'll surely focus on team based PvP first, which is the right decision even if I'd rather ffa.
I care more about exp loss and loosened rules like allowing bind camping and any level to be killed than item or coin being lootable. I hate safe spaces and anti-griefing rules in PvP because it makes the PvE too safe.
Screw battlegrounds and the like which is just pointless sparing. Without PvE to fight over there is no real point. Have robust PvE, turn on a PvP server, basic balance for OP shit like insta kill spells or perma CC, then let people hash things out like men.
Have a /duel command for all the pussies on PvE servers to slap fight each other with limp dicks, of course. But battlegrounds and PvP zones are lame and the bane of the MMO market.
