Most of the outrage stemmed from the fact that you are paying money for a Triple A game, but it has the grindy/paywall aspects of a free to play/mobile game.
Also they said at some point that during the beta they had examined player favorites/habits and priced things accordingly, people basically took this as, we are moving your favorites and the most iconic characters in Star Wars, Luke/Vader behind a massive grind/pay wall.
Regardless, the outrage and backlash, it succeeded. They already announced they are reducing the price of Vader/Luke by 75% from like 60,000 credits down to 15,000 and adjusting others as well (Luke/Vader are the most expensive).
And just to clarify, I haven't played a Star Wars game in like a decade, just wanted to discuss it a bit since I hadn't seen it brought up.
