Advice for 48+? 4x hunters boosted by 1x 60 hunter

[HHHHHunter]

Hey all, I'm currently boosting 4x hunters (currently lvl 48) with 1x 60 hunter on a high pop pvp server.

I've boosted through questing up to 48 and it was a pretty quick journey. I was thinking questing would be even nicer after level 48, but lately world PvP has been a cluster--I'm getting a little tired of the opposite faction repeatedly suiciding themselves just so they can disrupt my progress for the lulz.

Anybody boost 4x alts with a 60 single-target DPS main before? Looking for grinding spots when the PvP is too busy, I suppose.
