They gave us another do things campaign with FG in it. And they gave us random FG for maintenance delay. So, I hope they will not change.
In one hand, this new gacha mechanics make 6* really easy to get for free player. In the other hand, it's so easy to get them that you could be tempted to spend a lot of FG on every event to taste the pleasure of a new 6*... and buy them when you ran out of FG. And in a third hand (don't ask me how I do), the 55x mechanics reset when you did 55 rolls and got the 6*. It's really easy to spend 1000 FG to get your favorite waifu full equipslot and skill. And then, you will need more FG for the nexts ones.

To say it in another way, free FG were a deep sea of salt and paid FG were even worse. I don't know for you guys but I NEVER wanted to buy FG (not ecause I'm 100% F2P but because it's just too unfair and a waste of money. Real salt is cheaper). Now, with enough FG (paid or not) you can get anything you want. It seems more woth it to buy FG if you are not patient when you know you will have your 6* at the end and it can motivate players to spend more money. Espacially whales.
