Personal Story
It won’t affect much, and of the two variations I’ve done I’ve liked them both. I think the fighting one leads to a face-off against a bully, the drunk one leads to retracing your drunken steps to find something you lost, and the heirloom leads to recovering it from the Svanir. The drunk one was the most amusing to me.
This is all just the up to level 20 stuff, after that you will pick a sub-race to study and that will direct you until you get to the Pact.
Actually from lvl 20 you pick the order you want to join and then the sub-race to study, but it is like Donari said, your choices only matter for the first 20 lvls, the drunk one is by far the most amusing, and imo the more interesting quests, you can even end using a Charr tank in that path
(and the other 8 elite specs maxed too)
