Is it worth leveling rep with Eris at this point?

I just came back to the game last night after a few months' hiatus (I stopped before HoW came out). I barely leveled up my rep with Eris back when I was playing before; is there any point in going through that hassle of messing with her now, or should I just go ahead and focus on the new HoW stuff?

Thanks in advance, any advice is much appreciated
