If Potions of Speed didn't let you cast a full-action spell with your extra action and Quicken didn't allow you to cast two normally-full-action spells in a turn, then the massive exploits mentioned above would be fixed AND you, Icelyn, would still be able cast an action and a bonus action spell every turn. Is that not enough?
It is better than RAW but still not great to me. Having Quicken be a sorcerer mechanic that can’t be used for full-action spells does not seem good to me. I wouldn’t mind if a few spells, such as fireball, were excluded from Quicken but having all spells excluded is too much for me. I like how BG3 does it much better!
