Okay..you have finished all quests in your zone: they are ALL non repeatable.
What must you do then?
Oh you must venture into Cyrodil as PK (see PVP) fodder to access the quests there which are repeatable
Now tell me: there will be no would be PKs waiting for such fools (like me) who have no idea of PVP will there be?
Of course not! All ESO players are mature individuals who not "get off" on inflicting pain (however indirectly) upon others.
Then, I guess, that like me, after about 20 deaths and having achieved almost nothing except to get to know
the wayshrines and the repairers pretty well they may well consider logging out and just hoping that this was a one off.
But will it be?
I think that we will all find out fairly quickly and that most nonPvpers will end up not subscribing.
In other words if you do not like PVP then do not play seems to be the ESO message.
I expect a lot of flak but I don't see much above that will not turn out to be true as alas!! MMOs have taught me well that the lowest level of expectation is never low enough.
