It's not about that. It's about how the only reason the fight IS manageable is because you have to discover and use certain gimmicks.
I'm just saying, the whole reason D&D is a fun game is that you don't have to use gimmicks to beat enemies. You use your characters skills and abilities and spells and items to vanquish foes, and you use them smartly and strategically.
Im not opposed to using things like surfaces and environment. I just shouldn't have to use those things to win.
