While I agree 5e is not very well balanced, using 3rd party material as an example harms your point.
Should've explained myself a bit better; apologizes, it was a late night, let me see if I can break this down a bit easier:
5e has always had some fairly several balance issues with various races; whether that's making some races underpowered while other races were overpowered, there's been some difficulties getting all of them properly balanced with each other, so it's inevitable that some people would be trying to optimize the fun out of the game. I admit, I'm not the most innately familiar with DnD 5e in comparison to other people here, but even I know some of the races are a bit strong.
From what I've done with the core races so far, they seem to be more balanced than most other races - some are clearly designed more for certain builds, but nothing too egregious. It's when you get to the exotic races is where things start getting difficult; while I haven't looked too much into the races myself as of recently, the Yuan-Ti Purebloods were noted for being rather strong due to having both rather strong Poison and Magic resistances, which is pretty strong for a PC at lower levels and makes them pretty good anti-magic specialists. The Satyrs have/had similar issues, from what I've heard. Meanwhile, the Tabaxi are notorious for Dexterity builds, with the innate climbing speed and agility bonuses making for some frankly ridiculous Rogues and similar.
The third-party content just gets even more ridiculous. The Vulpin from Humblewood that I mentioned has the ability to use their Int. score for Dexterity roles, meaning that in combination with their innate Racial Score (2+ Int, +1 Cha), means that they can effectively get three bonuses for the price of two. Meanwhile, the Bearfolk from Ebon Tides are just ridiculous, getting +2 Strength, Powerful Build, +13+Dex Natural AC, a natural unarmed bite attack, and two different skill proficiencies, with the Shadowborn subrace adding +1 Dex, Darkvision, and multiple benefits for stealth while in darkness, all with absolutely zero drawbacks.
Bit annoying, given that I was considering using one for a build but didn't want to risk screwing up the combat balance; here's hoping Humblewood's 2026 expansion drops a more balanced race...
Of course, now WOTC is going way too far into the opposite direction, trying to make every race into the same generic blob for the sake of "equality"; frankly, it just begs the question as to why anyone would even want to play it. Creates a lack of incentive to customize and learn the game, frankly.
But for stuff that goes on player sheets? Forget excluding 3rd party content, I look at anything outside the PHB with a very long, hard withering stare. If I had a player I didn't know and trust (and who talked to me about it before hand) bring me a character sheet with third-party shit on it, I'd tell them that I don't think they are going to have fun at my table and should find another one.
Doubly so if they bring me furry shit.
Let me guess; bad prior experiences with coomers/furries? I'm not exactly judging; I've had some
bad history with them myself.
It is from Critical Role so I imediately assume its unbalanced faggot shit.
I haven't had the chance to play it myself, so I got no real clue. Looks to be inspired by Bloodborne, which is the only reason why it came to my notice in the first place.
