Reworking the DS power - Nuke Uncanny from orbit capped at 40% Rending and no more synergy with DoTs. Swap Finesse Stat with Critical Bonus Stat. That should lessen it’s effectiveness in horde clearing without the boost in Weakspot power and Attack Speed.
Working on the plasma gun - “Infinite cleave” locked behind secondary attack, fully charged Secondary attack caps at 25% Heat and caps damage regardless of how long it’s held before release, Primary/Secondary both get minor splash damage on whatever target stops the Plasma cleave, finally primary fire Overloads after 100% like Secondary.
