I don't know if its necessarily V, but I've swung towards being a lenient DM. My gf is at the table now and the advantage mechanic keeps things from getting out of control so I just sort of roll with whatever now. Like last night the guy playing a Monk was battling a thug in a flophouse and he wanted to use one of his attacks to throw a blanket over the guys head. Sure. If you it, then the next attacks have Advantage. Why not? If you think about it he was probably gonna hit at least two of his attacks anyways. Rule of cool they call it. I think the real new twist to my approach has been to not overcomplicate adjudicating that stuff. Just let it happen.
I sometimes come up with elaborate houserules to satisfy some simulatory itch, but I find that they usually don't go over well at the table. And if they don't, well then, why not shine it?
