have a shaman healing my 4 druids its is good

for a shaman team im not totally sure that another druid would bring that much more on the table, main reason i chose a shaman to heal was after realiseing what more the shaman would bring to a 4 druid team.

for a 4 shaman team i would go for a paladin speced with improve concentration aura, this will give you somthing like 55% interupt avoidance while casting, as well as different buffs BOW or BOK.
