Boosting - What to do now that they changed Scarlet Monastary so much?

[Asterix]

lvl 90 paladin boosting a group of 4 RAF Accounts.
Started with lvl 10 without quests in deadmines until they dinged to lvl 15 so I could get the quest.

Used the RAF Flying mount to get one of the toons to the next dungeon and used the summoning stone to get the rest of the group there
and just done each instance once. Usually they do one level because of the mob exp and 1-2 level because of the quest exp.

burning crusade is each instance once except of the tempest keep dungeons to get you to 68.
Although you can move on to WOTLK content: do the three tempest keep dungens first unless you want to
do azjol again and again waiting for the levelup to move on to the next dungeons.

wotlk is each dungeon once, usually you ding to 80 between halls of stone and halls of lightning.
you don't need the three ICC heroic dungeons.

and: don't miss the arena quests with 65, 75 and 84 ! They are close to the amount of a whole level of exp points !
