Looks like I was making underbog a lot harder than it needed to be. XP range is several times farther than I thought, guess I'm just used to the short RAF range from SM and Stratholme boosting.

I'm now pulling the first floor up to the second and killing them on the ledge. It prevents anyone from getting behind me and the toons seem to get full xp from that distance. Then I pull the top floor including the naga, and I made a macro to target and kill the murkblood healers first. With this method I don't have to use any cooldowns at all, just seal of light.

Probably possible to pull the entire first floor, and second, and pull back to the ledge and kill them all from there. Can use bubbles and maybe lay on hands if necessary.

Toons around 64-65 at the moment, still getting 450-600xp per kill. They're out of rested xp so it's a little slower than I'd like (maybe 100 minutes per level).... but I feel like that's still faster than trying to level 4 toons by questing/instancing. I was pretty fast with my shaman group, but pretty sure that was still a good 2-3 hours per level, and this is much simpler (although kind of boring).

On the other hand, I have two toons in the 71-80 AV bracket with the teleport trinket bound to every single key while I boost, so they just teleport home over and over. People report me for being afk but I instantly get ouf of it because I enter combat when the alliance are in the keep. It's cheesy but I don't really care, I've put in my time before.
