Onto my suggestions:
1. Short rests should be increased to 2 per long rest,
2. Players should have the option to turn on prompts for reactions. This will let the player choose to speed up combat with automatic reactions, or play strategically and choose when to use reactions.
3. Sneak attack can now be turned on and off. When turned on, the next time you hit a creature, sneak attack with be applied if the conditions are met. You don't necessarily have to add a prompt to this one either. Sneak attack doesn't usually need to be strategically used as much as reactions. But, you can add prompts if other people feel I am wrong here.
4. Better sneak attack UI. Perhaps you mouse cursor with change to something if you have sneak attack. Perhaps there will be text somewhere telling you that you have sneak attack.
5. Players can now cast spells like friends, thaumaturgy and charm person when in a conversation. It will be an option alongside the dialogue options if they wish to use them.
6. Cantrips no longer create surfaces. Firebolt is reverted back to its D&D version (1d10 damage).
In terms of my suggestion on removing surfaces from cantrips. I think if Larian desperately want them to have surfaces, then they should at least remove them from attack rolls. This will mean that if a player attacks with a cantrips, and shoots a firebolt at an enemy, it will not create a surface. On a hit it does 1d10 damage and on a miss it does nothing. If a player just uses a cantrip on an unoccupied space, then it would create a surface; so firebolt creates a fire, and ray of frost creates ice. This removes the ridiculous surfaces on a hit or miss, but keeps in the surface mechanic. I would still not like cantrips creating surfaces, but at least it makes them a bit more equal to weapon attacks.
1. There is NO LIMIT on how many short rests you can take in D&D 5e; they aren't ONLY used to heal hit points (there are a number of classes and features that recover uses at short rests, regardless if you heal hit points or not). As such there shouldn't even be a limit on how many short rests you can take between long rests.
2. I completely agree.
3. I completely agree.
4. I completely agree.
5. I completely agree.
6. I completely agree (and firmly believe that if they want cantrips to be able to create surfaces, it should ONLY happen when targeting an unoccupied space); I actually don't mind having non-cantrips creating surfaces (because those aren't at-will).
