[Suggestion] Oaks Minions

Currently nothing really fires on the oaks spirits. I believe archers and certain demigod attacks can only hit them. Priest cannot target them and siege archers cannot target them. Ranged demigods can hit them but melee ones can't ( imo should stay that way). Anyway my problem with the oaks spirits is mainly directed towered priest and seige archers. I beleive that both priests and seige archers need to be able to hit the oaks spirits. Its annoying when they can just float around beat the piss out of you and you can't even run to your creeps for help.
