Healer Frost.mage D.lock
R.druid(or any other healer) D.lock Ele.shaman
Healer Frost Mage Ele shaman
and now
healer moonkin + ele/destro/f.mage
those are the spellcleaves i can think of right off my head atm, Of those i listed, the LSD i think is the strongest and most retarded to handle, frost mage, warlock and healer i feel is slightly easier to handle due to dispellable ccs as opposed to cyclones, and frost mages fold under pressure easily.
But yes i'd agree spellcleaves are retarded atm with the burst potential, and it'll only get worse
