I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like “If this happens in your group, change it” as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
This has a lot of “stop enjoying that!” energy.
There’s no set of rules that a clever person can’t exploit or circumvent in some way, and min/maxers have been a plague on the RPG community since long before 5e. Frankly, if this sort of thing is a regular issue for you then the problem is the people you’re playing with. A good DM can roll with players like this and balance them.
Also the toxicity that is implied to exist by this post is pretty rare really. Even back when I was using Reddit, toxicity generally sank to the bottom of comment sections, and even more so here. When I got into D&D close to the beginning of 5e, some online voices on YouTube for example carried this toxicity but nowadays, most voices are far newer and friendly.
In general, most people are more interested in what happens at their table instead of all tables, and the rules are just guidelines to aid that.
