Guild Wars 2

Is there a minimum level? because it doesn’t appear this option for me
I’m in mac beta

It is the same as your normal character.

For WVW, press ‘B’ and pick the borderland/battleground you wish to queue/enter.

For sPVP, press ‘H’ and select the pvp tab on the bottom left and click ‘Enter Heart of the Mists’.

Just so you know though, your character is automatically set to level 80 with all skills unlocked, all 70 trait points, and different gear for sPvP.

For WvW, you only have the same skills/traits/gear as your character does in PvE, and any experience/gear you get stays with your character if you go back to PvE. Your stats are all scaled to level 80, however, a true level 80 character will be more effective in combat.
