Q u o t e: Softcore PvP is hardcore PvP practice mode. No serious hardcore PvP player is going to step foot into a hardcore arena until they've gotten a few hundred hours of practice in softcore under their belt. Don't forget the gear farming, too.
And don't forget the team element. We are looking at 3 v 3, so each game loses 3-5 dudes. You MUST have a practice mode.
You better be hardcore to play hardcore.
