Bricked Character help please

So.. Ive been playing the Early Access with great joy so far, rolled a warrior and been rocking through story and early endgame. Lv70 now, ive felt like map clears took way too long and looked up a build. respecced to it using all of my gold (like 400k gold yikes) and used all of my exalted orbs to get some matching gear shown in the guide. issue is, my character is BRICKED now. i went from being able to easily clear t5/6 maps to not even being able to defeat the mobs in act 3 cruel utzaal now ?????? ive no idea why the build isnt performing as shown in the video, but having used all of my funds to copy it and it not paying off is absolutely stupid. all i want is a way to go back to my old build, so does anyone know how to quickly get 400k gold ? ive tried rolling a new character but it is just too slow and i dont want to waste 30+ hours to reach endgame again. please help and share tips if you can. WHY IS RESPECCING SO STUPIDLY EXPENSIVE ????
