I recommend Niara’s
Ka’chu’ka thread.
After crushing the Gith patrol with four naked level 3 PCs, Niara gives her conclusion.
Four characters, level 3, no class abilities, no spells, no skills, no armour, no weapons... just Larian's homebrew, and it was game-breakingly brutal. This is a problem.

The trouble I have with this is that I can illustrate this issue, but we've already seen Sven and Larian's public-facing philosophy. They'll look at this and go “Isn't that funny and cool and fun! There's no problem here, it's great!”
It's not fun, it's not particularly funny after the first time, and it's not cool; it destroys any concept of game immersion, it breaks from the tone of the story in an aberrant way, creating a jarring juxtaposition of different conflicting elements of the game, and even within itself, it drowns out all of the other game systems that exist, rendering all player choices meaningless and obsolete in the face of the general universal abilities that overbear them. Resource-costing class spells, abilities and features are obliterated and pointless when a resource-free universal option is available to everyone that is faster, stronger, safer and more effective than any of them. In fights, there's no real need for tactics or careful decision making – the general strategy remains constant and works with brutal efficacy, almost regardless of the situation.
