The complaints from players about Products is just theory crafting at this point. It's impossible to tell from the 2 months in-game if the new Product system is good or not.
This is a massive risk for the game, and I am willing to give it a shot because its flaws are rather obvious, and the positives, I think, could be very good.
The best thing is that every promotion feels unique and has stuff you like or maybe not like as much about it and are forced to do. This is, in my opinion, great. Literally EVERY single promotion I played in TEW 2016 was booked the same with some very minor differences, mainly regarding things like having to put match aims on. My template for a show was the same across the board.
Now, try booking TCW, a company that likes long matches and doesn't care how long angles are, to a company like USPW that yawns at every thing you do. It's great.
I totally get all the reservations mod makers have about this.
The product system in 2016 was kinda dumb. RatedRKO brought up the dumbest part of it-- you just change Comedy from low to very low to get a product that doesn't have something that doesn't perfectly line up with what you want, smile, and start bookin' away. This system has a lot of nuance, and I get that people love customization options, but sometimes it is fun being forced into things.
That said... I do think something will be added in to customize the products. I don't think Adam realizes how much of a pain in the ass it will be dealing with it down the line.
