Not missing the point. You just have no response besides restate Larian does cheese, as if playing Dice-A-Rama with wet noodle spells that hit for nothing assuming they actually land, consume a spell slot, and can't be weaved for combos (because of concentration, say good bye to the thought of entangle into moonbeam) doesn't make casters feel like hot trash.
And more to the point, what's the use of Shadowheart if she can't layer buffs and debuffs? With the +1 mace she is hitting for a pitiful 4-7 damage with usually a 78% chance to hit from backstab. Or maybe you're referring to her permanent 50% chance with Sacred Flame that usually does even less damage than her pitiful melee and fails saving throws 24/7. Can't use her divinity skill without removing bless, and the only reason to bring her is to be a bless bot. 60% chance to dome some good damage with Inflict Wounds at the cost of a spell slot, too bad it's melee and Lazael has 75-90% chance to hit foor the same damage with her regular melee that doesn't eat up limited resources.
You are so obsessed on how you want to play and what you want, you are not seeing what Larian wants. Larian WANTS you to cheese the fights. If they didn’t, why would they include the cheese mechanics? Which brings me back to my point. You should be frustrated at Larian homebrew and not request more homebrew that would break the game even more.
How about you dip Shadowheart’s weapon? Now you get an additional 1d4 on the hit and another for burning. Make sure you maneuver behind the monster so you get advantage. She now does damage on par with everyone else and she gets a bonus AC due to her shield that Lae’zel does not have.
Concentration spells and saving throw spells seem underpowered because there are Larian mechanics that make them weak.
