Way too good.
You've spent way too much time doing this than it actually helps, unfortunately.
Due to the insane low difficulty of each and every dungeon in this game, tactics are basically overthrown and completely useless.

needed tactic which is needed for every

Step 1. Tank the boss facing away from the camp.
Step 2. Deal damage.
Step 3. Heal the tank.
Step 4. Don't lose aggro.
