Guild Wars 2

Are having a return to GvG?
That was by far one of my favourite things from GW1, second only to being able to watch other high rank GvG matches for tips.

The Guild Halls are introducing an “arena”, in which groups of players (in guild teams, or not) can battle against one another in up to 4 teams.

So some form of GvG is being introduced with Guild Halls. Though, it is not the same as from GW1 as far as I know.
