I just thought it might be good to actually test it as opposed to just asking them to do it. One of the arguments against 5e being more accurately obeyed is that if they do this the game won't be as balanced and enjoyable. So they need to nerf things like sneak attack and allow backstab and barrel throwing to make the game fun.
I personally like some of their house rules. I like poison clouds and greasing and setting fire to enemies and some of those types of things, but the whole backstab thing where Lae'zel plays Hulk Leap and Slash is ridiculous. Either make enemies easier to hit by lowering AC or give me better weapons so my chances of hitting regardless of facing and height are better. It is actually more frustrating for me to constantly make sure I position key characters right to avoid backstab and enemy height advantage than anything, and like someone said, I didn't even realize these little strategies in my first few playthroughs. So enemies were beating the tar out of me because they were using them and I wasn't.
They could experiment with giving a slightly higher Proficiency bonus progression to increase hit rates 5-10% and make proficient skills work more often. Perhaps balance the extra HP loss by giving a 3rd short rest, or an automatic Short Rest after every encounter (unless you flee so it can't be exploited).
While lowering the enemy AC only helps attacks that target AC and effectively nerfs spells like Sacred Flame that target Saving Throws, a Proficiency bonus buff would be equally beneficial to everything. Hence less balance complications like we are already seeing with Sacred Flame, Poison Spray etc. after goblin AC got lowered.
