Yep, they remade all the skills, created a new mode, but they couldn't bother to add a small tutorial.
(and we'll not even think about some UI function to automatically replace the old skills in the hotbars)

Before being able to queue for PvP, players should complete a quest that asks to 1) deal damage to a training dummy in the wolves' den 2) use Recuperate.
And when they do a big revamp of pvp like 6.1 (which won't happen any time soon, if at all), all PvP is locked for all players and we have to re-do this quest to unlock pvp.

It's not much, but still better than nothing.
