I would not look at it as a dismissive comment for you, more that the poster is annoyed that RPGs are in general quite bad in making simple and complex balanced in a good way. (Or sometimes also just the perception of RPG players).Off the top of my head? In 5e they put out a "Brute" subclass for fighter in Unearthed Arcana. I felt it was a good start, but they didn't develop it further into an official release. It just straight up does more damage and gets better saves, but doesn't have anywhere near as many options as something like the Eldritch Knight or Battle Master.
But nah. I tried this site out for a day, but maybe I shouldn't come back after this. Dismissive comments like yours are making me remember why I left forums behind.
In 5E in the end the more complex classes (casters) are stronger than the less complex ones (martial), and even for fighter in the official releases the more complex classes are stronger than the simple ones.
I think the reason the Brute subclass never got released was most likely also because its hard with making players happy with a simple subclass. (Making it not too strong and not to weak). Anway, I never looked up the Brute subclass, but you made me wondering, will do now, thank you for mentioning it!
