For the most part I agree with OP, but I dont get this "poor rogue" thing. Maybe I do something wrong, but in my games rogue is always powerhouse of the team damage-wise. Dual wielding rogue with 2 +1 short swords hits like a truck with basically 4 attacks every round (3 if i need to move a lot). So why exactly is rogue nerfed in your opinion? Is he some kind of god in paper 5 ed?
No I just feel like the core mechanic of rogue just got sort of handed out. Kind of like if just everyone got fighting styles. Also I do think the way that thief works should actually be nerfed. The fact you make an offhand attack by default, and again as a bonus action, and AGAIN as a thief is kind of nuts. Action economy is everything in 5e and the way the handled duel wielding so far isn't idea. But yeah that's a balance issue for sure, but as far as the Cunning Action stuff goes I think it also makes the action economy a bit strange to give one of the rogue's man gimmicks to everyone when it should have (in my opinion) stayed how it was.
