I hope this doesn't mean they've decided to implement Pathfinder to unlock flying.

In other words, his comment is so vague we've got no way of knowing what he was thinking about when it said it. Any number of things could fall under the heading of "less stress-free".

Maybe they're going to double down on how annoying it is to try to purchase the game and expansions from the Square Enix store.

Maybe FATE timers are going to be reduced from 15 minutes to 8 minutes like a few of the ARR FATEs.

Maybe they're finally going to start killing off Scions in the MSQ instead of equipping them with plot armor so thick nothing can touch them so some players lose some of their besties/waifus.

I would highly recommend not reading anything into it because we don't have enough information to know what he's referring to.

I also wouldn't expect such changes to start happening until 7.1 at the very earliest.
