The Healer feat sounds good but healing potions are everywhere in BG3. I'm finding new potions faster than I can use them with the main source of healing being Short Rests. If actual 5e rules were being used, we would be using potions to revive PCs.

Then we have the ridiculous potion throwing homebrew. Which table ever used such an asinine house rule? As long as you can throw potions at people to heal or revive them, such feats would be even more redundant. You can even throw potions from another character's inventory. They've made it so convenient the player doesn't have to think who carries what and you don't even need to get close to the downed character anymore. And even if you did Larian are spamming the game with movement / haste / teleport items.
