That's a problem with you not being good at the game in general. That's a reason for difficulty settings, not a case for keeping in a badly overpowered skill.
I admit that the game is very challenging right now, and I do have to think and plan carefully to deal with large fights, and I have to be cautious and know when to use healing items, and pick what buffs/debuffs I should use, and I get it wrong a lot of the time.
