The issue being shown is with just strength and the homebrew, one doesn't need anything else.
Which is a big problem.
The homebrew is too strong right now that it makes class features semi obsolete. (Technically a Str Thief Rogue would actually be the best shover cause they also homebrewed two bonus actions but I digress.) Normally in 5e class identity is strong enough that you in some way have to play to your class's abilities or apply them to move forward. Here, it is being shown that BG3 can not just be beaten classeless, but is also EASY to do so and not a challenge that people would assume.
