Even if Burst of Flames were weakened further, it would always be possible for a Mage (or Warrior with Brutal Smash) to do a lot of damage to a boss by inflating their mana using Fix Character Values and casting the skill many times. I wouldn't say that the skills were out of control, but that the player was. ;) Although in situations where the party doesn't mind and the player finds it motivating or enjoyable, we don't think there's anything wrong with a player doing that. If your party doesn't want quests to progress too quickly, you'd be quite justified in asking the player to limit their use of the skill. If the player would prefer to keep casting the skill often, they might choose to find a party with a similar play style to theirs.
