Thanks for feedback.
Although I have only 2 options as char setup.
Either pala + 4x shaman
or
Pala + Priest + 2x mage + lock
Everything beside pala is already 60 and I will level pala once pre patch hits. There is no other option than any of above mentioned teams.
I know, it would be easier with locks for example during leveling as you hit hellfire and thats it, repeat after kills/15s etc. Mages can use blizzard too, but not that well efficient like AE + FS (more effort required). At 70 with SoC and locks gonna be the same as shaman, u need to spam and spam, but probably you will need to switch target as SoC might not blow up before 2nd one will reach target, which for me it would be even more difficult than shamans. That is why I thought 2x mages will be enough to force blow up SoC of single lock so switching targets will not be needed.
But overall, my main focus gonna be heroics, meaning, there is no option to pull many mobs to AoE them down, so any AoE lock / mages will lose value compared to shamans, which can get down grps of 2-4 mobs very quickly.
But I loose utility cause of that compared to priest / mage / lock team.
This is my main concern about choosing proper team.
