But you don't have to do it, if somebody really wants to place 40 barrels and blow up the goblin army why not. If you do not want that in your game, then don't do it. Why would it matter?
It breaks the balance of 5e regardless if someone mass loads them pre-emptively.
I am not saying the game would be better without them, but giving feedback suggesting they tone them down. Unlike DoS2 we don't have phys/mag armor to soak up the extremely high amount of damage coming out of both the explosion and the surfaces they leave in their wake, and this goes for enemies as well.
And if your suggesting that people just ignore them entirely that's all good and well but the enemies don't ignore them, so you either use them against the enemy or the enemy uses them against you.
