This is a simple question, but I can't find a decent answer.

I have recently started to play Eve Online as a Caldari capsuleer, and I am currently doing lvl 3 missions in a Drake.

As I didn't pay much attention to faction standings at the beginning, I am now at -2.03 towards the Gallente Federation, and I'm starting to wonder if I should try to get this standing positive again.

As far as I have understood, the only reliable way to gain faction standing, apart epic arcs or factional warfare is doing storyline missions, which is going to take some time to go from -2 to 0.

So, does it really worth it to manage to get a positive standing towards all four major factions ?
