As you may or you may not know, Feerik has stated that they completely ditched Berserker class. Berserkers were what Berserkers should be - pure, reckless damage (physical, magical AND direct) with no regards to defense. Too bad Zil marauders do better in all 3 types of damage while having some nice utility too.
So, my idea is as follows:
ditch Berserkers as a class, instead make them a caste and add, say, Warrior/Mage/Priest depending on a character to current Berserkers. Since they morph into bestial shape when enraged, why not add them a Beast race when they obtain the rage bonus?
Keep their current cards, just make Berserker class effects (like Rage bonus) into Berserker caste effects.
And this also gives us the chance to update on of other outdated characters,
The Sachem. Something like this:
Elfine
Mage
Berserker
Rage: The Sachem changes appearance and becomes a Beast/Warrior which printed attack equals 7/10 and he deals an additional attack that equals his printed MIn attack.
The Sachem obtains his rage bonus until the end of the game when one of your characters die.
Turns 3 and more: Attack +1 for each of your dead characters.
Maybe even release another Sap berserker to go with
The Sachem and
Yulven. Could make an interesting strategy with
Bestial Power and
Butterfly Collar considering that these two characters alone have different races and would obtain Beast when enraged.
