OK, let me see if I have this right. You would rather level up a new shaman from 1 to 30something just because you don't want to have to level an occasional yellow bubble solo along the way? Seems a little backwards to me.
Also, the higher level you are, the more your regeneration is as an iksar. Your racial regen will bump up at 50 and again at 60, I believe. That's why Iksar make great shamans and necros. I have an Iksar necro, and she's a blast to play. I have virtually no down time at all and level very quickly because of that. Being that you group, your group will all benefit from you being able to regen mana faster because you can canni more.
Stick with the iksar. You won't regret it later.
