Ideally, players shouldn't be on Haven too long and its intent is not to teach them the entire game. This shouldn't be done by any timer, but rather, a lack of things to do on Haven once you master basic mechanics. Going to Myrland for the first time is the next step of the new player experience. That is where they learn PvP, and loss, and griefing. A tutorial can't cover such things perfectly but it can do a bit of it.
I'd also look at EVE for inspiration on this one. First off, I think you actually get podded as a part of the tutorial these days just to teach players the death mechanic and the idea that ships can be lost. A mission that requires you to die and lose your stuff isn't a horrible idea for MO2 done properly. Second off, EVE kind of guides you toward post-tutorial starter missions to further your learning experience. If there are concepts you need to be on Myrland to learn, then have a few options for things to do once you leave Haven.
You don't need to experience PvP, loss, and griefing during the part of the game they are teaching you how to sprint and jump.
