Adding on to what Dras said, eventually you will get to the point where you HAVE to build a certain thing a certain way for it to work. It kinda removes choice in the matter.
Being able to change points via Tournament PDFs is good for the game. Now FFG can't constantly print changed cards which is understandable. This box of upgrade cards is really generous for what it is. At least 1 copy of EVERY card in the game already out? Sign me up for that. It's not like people will force you to use the new cards either. Just keep the updated Tournament PDF on your phone or print it out.
If you just play the game at home, then just use the cards you got.
