Shaman Totem (SP)

I was wondering if its possible for a on equip spell to be added to the shaman SP idol (All of them or just mainly x7 and donor one) Currently druid SP idol gives a bonus when using moonfire (giving crit) or using rejuv (giving sp) But the shaman one only gives a bonus when using chainheal which is kindof useless for elemental shamans :) Thanks for reading

both of those equip spells are useless anyway, don't know why they even added them
