Sure, that's fine. It's an arbitrary line in the sand that I don't think holds, because I doubt you're against houserules for you own games. To be fair, though, this line of argument reads like claiming that the pizza you eat is the best pizza, only to find out you've only ever had 1 kind of pizza from one outlet and not tried anything else. It's very possible that, even if you did, that would still be your favorite pizza (I mean, I still very much like 5e even after trying other games), but someone that has tried other pizzas my find how you argue that the only one you've tried is great pizza a bit flat. "It's got sauce!" Yeah, pizza does that, is it good sauce, though? "It's sauce!" Okay, but is the sauce doing what you want? "It does sauce things!" Okay....
