"5e of course is a terrible system that requires House Rules and a good DM to allow any form of "Tactics" at all"
wtf? 5e is a great system that puts the focus of the game on actual gameplay, combat, role-playing, etc, over number crunching and mathing. I realize the everyone on forums like this love to shit on Critical Role because its popular, but CR is a PRIME example of how great 5e is. 5e doesn't allow for tactics? patently false. And as far as house rules...people made house rules for every earlier edition of D&D as well, so saying you use house rules for 5e as well is a moot point.
