Heal helps more, in the case of mausoleum and graveyard. You just need to figure out what weapon you and your team should use. For mages you need flame forged staff for mobs and dragon hunter staff for boss. While you use heal regularly it saves team from dieing situation spamming pots is not easy while you stun etc. It is your choice if you want to use or not, IMO heal is useful for safe running
