Multiboxing dungeons advice

[jbox]

Hi. I am new to this forum and multiboxing.

Since classic Launch I've been leveling 5 Horde toons: Warrior-Prot, Mage-Frost, Lock-Destro, Priest-holy, Rogue-Combat. I have been struggling with leveling, so far I am level 42-43.

I've been having problems in the instances whenever there's a big pool of mobs and I lose aggro, I am not fast enough to change to my Mage to frost nova and AOE down alongside my Lock. Most quest are recollecting quests and take hours to complete for my 5 characters.

I have been questing and completing most dungeons. I am able to clear Scarlet monastery, Uldaman I only killed the mage-quest-boss, RFD I can clear everything dying with the skeleton boss army, I can't finish the escort event, and now I am struggling with Maraudon because all the demon rogues sap me and go after my casters.

Any advice you can give me? How can I level faster? How can I pull the rogue satyrs in Maraudon?

Thank you and beg your pardon for my English.
