Well, I've decided to level up 3 more shaman to allow me the option of running my current group or Smara + 4 shaman and have come up with the following boosting plan for the alliance side, anyone with experience or suggestions on improvements feel free to add comments

Will be boosting with level 70 prot paladin, 9k hp unbuffed, 497 defense, using sporegaar shield + thorium spike

1 - 10 - Newbie zone
10 - 15- Deadmines
15 - 20 - Stockades
20 - 40 - SM
40 - 50 - BRD
50 - 55 - Scholo/Strat
55+ - Outland

I figure once I get them to 55 I can group them with Smara and Baanmee and get them through the lower instances fairly easily still and then from 60 onwards they can actually contribute as a full team. Once they reach 70 if I gear them around the same speed as the rest of the current team I should be able to gear Smara up more easily (given the pew-pewness of 4 shaman shown in videos compared to current team) to help get him more overgeared for instances and thus make it more easy to drag everyone else through them as needed.
