Yeah, I'm hoping they finally figure out the tutorial balance in Wilds. Earlier games had next to nothing for tutorials, and you pretty much had to look outside the game to even understand the basic movesets of the weapons, much less how things like skills work. I think they overcorrected with the recent ones though, it'd be nice if they could get a little better about introducing information in the world instead of constantly stopping the action to make sure the player sees it.
But yeah, absolutely do not use the OP armor, you'll only ruin your fun and then have a really hard time once you get to the real fights. The main reason to use it would be to power through low rank if you've done it on another platform or something.
Yeah, I guess they should have just locked all of it behind a paywall so entitled people don't get worked up over not getting everything for free.
