I have a concept for Berserker, like the name says, going berserk should reward constantly engaging in fights, as in the more you fight the stronger you get, so like some Ascendancy Points I made up : Blood frenzy: For each enemy killed in the last 5 seconds, gain 0.2% increased damage, against Rare and Unique enemies gain 1% increased damage. No stack cap. 25% increased Attack Speed and Critical Chance against Unique and Rare Enemies. Blood Boil (Requires Blood Frenzy): Enemies explode on crit in an AoE, dealing 5% of their max HP to all enemies in an AoE after 2 seconds. Stacks up to 3 times for 15% max HP. Does not work against Rare or Unique Bosses. 25% Global Critical Chance increase. Unkillable: Gain 10% Damage Reduction if there are 3 or more enemies near you. 25% Chance to gain Endurance charge or Frenzy Charge on Crit. Blood Funnel: For every enemy you killed in the last 5 seconds gain 0.2% max HP regeneration. Against Rare and Unique enemies gain 0.5% regeneration instead. No stack cap. This is just something I had in mind, chain killing groups of enemies and sustaining itself in fight is something that a Berserker should do and not being in a fight should not punish, but being in constant Fight should reward player with damage and survivability. Just my 2 cents.
