So I recently hit 80 on all my chars (the ones in the sig)

I did a lot of 5boxing pvp, but I have had 0 luck finding raids that will let me box... I can't even find a VOA that will let me box.

So I started solo gearing them (1-2 instances per char)

to compare them this is their be.imba scores now with main specs and offspecs listed in that order:
Subbs 514.23 - Ret / Prot Paladin
Heartplanetr 439.44 - Resto / Ele Shaman
Fireplanetr 362.07 - Frostfire / Arcane Mage
Waterplanetr 284.79 - Ele / Resto Shaman
Earthplanetr 202.09 - Ele / Resto Shaman
Windplanetr 183.45 - Ele / Resto Shaman

So I have 2/5 geared up good enough to start multiboxing heroics (should be around 2.5k-3k dps depending on the fight), the resto shaman is at 2k-3k hps also depending on the fight.

Is there an easier way to gear them up? should I just grind AV for PVP gear and say screw PVE gear?
