Healing aside, throwing potions effectively lets any PC cast Haste, Invisibility, Sleep etc... None of these effects require concentration, saving throws or even line of sight. Throwing potions seems entirely divorced from the rest of the 5e system.
It seems to be a repeating issue with Larian homebrew that Saving Throws or other 5e rules are completely ignored. The surface spam is guaranteed damage (which is why Concentration spells are basically unusable). Ropes and chains don't have AC and anyone can simply choose to cut one with any ranged weapon. Falling boulders don't allow Saving Throws. Astarion's gimmicky vampire bite has 100% to hit with a meme-like "happy" condition which contributes to making vampirism seem like a
funny thing. I don't think games should take themselves too seriously, but that's way too far on the other end of the spectrum where even horror is just another meme. Do Void Bulbs now allow a Saving Throw?
Why does an arrow that misses still detonate an AoE right on the target? It missed. How does an arrowhead pack gallons of acid to create a pool?
And good point on the non-healing potions. Potion throwing is a GREAT option, but the mechanic needs to be to catch them and DRINK them on your own turn. Turning all classes into semi-spellcasters with an abundance or scrolls and potions with "creative" ways to use them is not cool.
