Not really *any* form of convenience or quality of life adjustment, but the majority of those that either reward or promote lazy engagement/non-engagement, certainly. Rewarding non-engagement promotes non-engagement, and that's bad for any game in the aggregate sense as concerns the cultivation of dominant strategies. I also wouldn't really consider it a "negative" on the convenience of unattended flight insofar as much as I would a converse "positive" on the attended model. Now cynically one might say that's a distinction without a difference, but I wouldn't agree - unattended flight speed has been the status quo for a long time now, and Dragonriding offers vastly increased speed for the price of limited endurance in the form of Vigor and the requirement of player engagement to keep at it. So you're being rewarded for your engagement, not really punished for opting to hit autorun and minimize your game for X minutes (or you would be in the context of both being readily available options).
