My experience playing Baldur's Gate 3 has left me regretting ever using web over grease. (Patch 6)
How web currently works from my experience is it creates a area of difficult terrain. When cast or entered if you fail a dex save you're retrained for 1 round (ending at the start of your turn rather end). It can ignite creating an area of fire and requires concentration.
Grease is a non-concentration spell that fills the same area (Is half as big in the board game), has a dex or be knocked prone (Which is arguably a worse debuff than web due to them starting their turn with less movement outside support from items protecting you from web, and if you walk into the field you lose your turn rather than getting disadvantage on attack rolls).
In the board game web's strength was you'd be restrained until you used an action to break free, burned the web or teleported. Neither the starting in web retrains you (though the effect happens instantly when you cast in BG3) nor does grease force the saving throw while ending your turn in it.
You can argue that prone condition as a debuff when applied on your own turn is too strong, shouldn't it work more like the board game? Losing your action and rest of movement if you fall prone on your own turn is pretty bad. Perhaps you could add the ability to spend half your movement to stand up, and/or let people keep their action but impose disadvantage on all attack rolls.
On another note, it's pretty cool that all the npc's now jumps, but leaves a lot more desired from the difficult terrain from both web and grease when enemies just jump out if they start there. (I know it's not worthless as they lose a bonus action but it kinda feels bad. Though I can see the balancing aspect.)
That being said I do immensely enjoy your game. Keep up the good work.
