Guild Wars 2

Or will it be like current personal story where you cant go back and repeat it on same character?

im pretty sure this will be the case.

HoT is practically Personal Story Part 2 merged with Living Story Season 3 in one package I guess.
I’m sure we will be able to repeat all the story relevant instances like we were able to do so in LS2 to replay them for achievements/rewards.

Also don’t forget, they are working in reimplementing LS1 in a similar way like LS2.
If they do that for LS1, I tzhink it should also not be a big deal to do that for the <personal story of the Main game to make it replayable to add to it for the replay run achievements and better rewards that are better fitting for a maxed out character, than for one, thats climbing up on the way to level 80 on the first playthrough

At least thats my hopes, that they overhaulo the complete game after the initial better system of LS2.

And please, should they do that, then overhaul also these boring emotionless/mimicless theatre 2,5D conversation screens where we see nothign but just two characters standign in frotn of each other and a boring background… this is so much 1990 Game Design and not fittign a a game made in 2012!! Story telling should be really more modern in this game.

but thats an other topic xD
