Honestly, R1 titles have almost no meaning. They're so easily obtainable, along with ridiculous amount of ways to exploit for them. Most, if not all of the great players in this game could almost careless about R1 titles. because they know that they don't mean too much. Back in BC/Wrath they meant a good amount, but now they're almost just useless. Yes R1 titles are nice, but no one really cares about them except 1600 rated players when they fight against you in an arena and go "OMG He's a Malevolent Gladiator, He's really good!" The current state of PvP right now is so disgusting that the titles mean nothing.
Take the honor you have and purchase Justice points with them, and just continue to level through BG's. Yes you do lose some on transfer, but when you can turn the Justice Points back into honor with the 375:250 conversion rate. It's better than just continuing to do BG's while you're capped.
