I'm not reading through all the posts here, so if someone else has this idea, cheers.
Not knowing how exactly the catch up mechanic with work, I would propose a condensed campaign mode. This could still be optional to play, after you are boosted to whatever is consider the appropriate, new starting point is. But, I like the idea of being able to move through the story content at a brisker pace. Campaign mode would cut most of the filler levels, and move their story content into a smaller number of missions. This could help get through the content faster, while getting all the story and upgrades.
I think the idea is justified, given just the reasons the devs state. And I do see it as reasonable to charge for this option. As for those concerned about this turning WF into some greedy pay to win thing, I just don't see that as practical. A player with the bare minimum requirement to play all the content in the game, will not be that comparable to a seasoned player. They just will have the tools necessary to play all the content seasoned players slowly unlocked. Do personally think people should pay and skip content? No. I think the journey is its own reward. But again, the dev pointed out the game is being hurt by the climbing wall of content it takes to play new drops and to join seasoned players in late game content.
