I would suggest running red line. It requires more thought, trap placement, using CC, etc., but it's the only useful line once you hit 130 and it makes sense to start building your LI's towards it now and getting comfortable with it so you don't have to re-learn your class.
I started this game at launch and the original hunter looked more like red hunter today. Despite me always complaining about how things were better in the old days, I actually preferred blue line hunter, a lot. I loved my blue line hunter, and continued to play blue line even after Vastin and team destroyed it. Eventually blue line just didn't cut it, pre-most recent hunter buffs a blue line hunter was like taking a blue guard into a group as DPS. Although the buffs helped us quite a bit, blue is still completely useless in every context except slayer deeding in landscape.
I am actually enjoying red more now, even if you are doing solo landscape or PvMP red is viable and imo the way to go.
