60-80 Leveling Question

I have leveled a few teams to 60 by making use of RAF and making use of my main to boost them through instances. I now plan on leveling 2 of these teams to 80. I have read a few other threads and most people seem to think that questing is much better for 60-80.

So I guess I should focus on team 1 and level them to 80 via questing. Once team 1 is at 80, grind some gear and then get heirlooms sent to team 2 and then level team 2 the same way but with heirloom gear.

Whilst leveling team 1 and getting hierloom gear, I thought it would be a good idea to use team 2's rested XP and do random dungeons with them as and when. But if using teams 2 rested XP is good, would it be a good idea to level both teams in parallel through random dungeons, alternating between them for the rested XP?

I realise this would take longer, but I'm not in a rush and I can do other things in between as I am leveling 2 chars from 60-80 manually atm and I am still within my RAF period so I can make more teams.

I guess I want to know whether leveling 60-80 via dungeons with rested XP is better than questing 60-80 looking at it from the XP / hour point of view.

I think you should do both. Quest and be in the LFG queue, then when it pops, do a instance. That will give you an idea what you will do when you hit 80. Mostly do not get bored with any one facet of the game, it is easy to do.

Unless you don't like/want that, you might consider doing AV's as well. It's a fun break away and gives a nice amount of xp / honor as well. If you frequent av's you will reach the honor cap when you hit 80. If you are not into pvp, buying 35 epic gems (zircom, cardinal ruby, ...) and sell them for 175-200 gold each (on my server) might give you a nice amount of cash as a fresh 80.
