Um, well, he's right. You can only autotrain in LB, but that's not your question anyways.
With the addition of New Frontiers, it seems like range is EVERYTHING in RvR now. Which is why I suggest True Shot 3. It's a 50% longer range with no damage bonus that will penetrate and break bladeturn. When you can do that every 30 seconds, you've definitely got an advantage.
Otherwise, I suggest concentrating on RAs that will develop your archery skills, i.e. falcon eye. That's just mho.
