Berserk and Charm

[Forefall]

I'm getting the feeling these are borderline overpowered. Berserk you can get so early level and it makes my knights amazing at crowd control. Is this intended? Will it somehow stop being so overpowered? I'm worried about a gambler with charm being even worse. Should this be a "house rule" not to use these abilities?

The Gambler's Allure has a 75% success rate, so it's not guaranteed like Taunt. It's up to you on whether or not you want to make use of the abilities. Later on, you'll see more and more enemies immune to Berserk or Charm, although it still stays powerful in the situations where it works.

Yep, unless enemy has innate or item immunity to Berserk (even if they do, its usually only few), it's pretty much 'I win' button: 1 action to prevent 2 enemy actions and probably cause damage due to indiscriminate attacks in process.
The only universal counter, Barriers ,can be efficiently dealt with by double cast Druid's Dispel or Templar's Cleansing Blade.

Why two enemy actions? Remove this buff is only one action.

Charm seems more potent because you don't have to manage the distance.

Not sure if it's a bug or a rule I don't know or I didn't noticed well the messages, but I have seen enemy charmed attack friendly unit, and right after lost the Charm state.

To rebalance berkerk, enemy AI shouldn't be disabled, a target is forced but then the enemy should has the full AI and all possibilities.

For charm, there's no damages to enemies, but enemies have limited support abilities. More mana requested perhaps, at least for the Vampire charm.
