I don't see the big deal about being able to dip an arrow in fire to get a bit of fire damage added to the attack. Also, I find managing ammunition for weapons tedious. Unless they are super special arrows/bolts, I really don't want to mess with it. I never track ammunition in table top D&D.
-Agree with the time taken to remove boots. Now, if the boots were just in your bags, withdrawing them could be a free action. But if you're wearing them? Yeah, they need time to be removed.
-I'm not sure how much more sophisticated they can make the light/shadow system. To take silhouettes into account seems to be a lot of unnecessary work imo. It would also make things tough on the player.
-Alignment is absolutely NOT essential for D&D. 5th Edition has moved away from it so drastically that it's barely referenced anymore. The focus is on character choices and character agency. Instead of saying, "What would a Lawful Good Cleric do in this situation?" it becomes "What would MY CHARACTER do in this situation?" Alignment puts a character into an unnecessary box. Just think about what kind of character you want and stay true to it with their actions. No doubt BG3 will be tracking your morality in one way or another.
Another thing that worries me is Shove, Jump, and Disengage being bonus actions. Disengage being a bonus action takes that unique utility away from rogues specifically. Shove/Jump being bonus actions skew the power curve towards classes like Fighter and Barbarian as they get bonuses to Shove.
- One thing is to tie a piece of cloth imbued with oil to make a burning arrow and it require time to craft (not much but is anyway time), another is to throw your bow in the fire and hope to obtain a magical weapon and not some piece of coal... so, maybe rethink the visual effect of the action and making it cost 1 action: less "the bow is on fire" and more "flaming arrow"
- Ok, maybe, is to much for the system to take silhuette in account
-Pathfinder Kingsmaker did a good job into taking in acfcount the alignment variation.
