Surfaces as a concept are fine. Cantrips leaving them behind and 99 million barrels beeing in such a small area is not though.
Feeling smart and awesome because you use these in your favour to win a fight loses its charm when you can do it in every bloody encounter.
Any cheese we can do to the enemy like plopping down barrels from our inventory and blowing them up, I want the enemy to be able to do to us. They should use their own barrels to their advantage.
