I was planning to get it day 1, but may have to delay it couple of days (for some personal reasons). What about all of you? How many of you are getting it day 1?
Other than one scripted one it makes you do as a tutorial when they become unlocked they're optional, can keep it in your back pocket at 100% charge until you feel like manually hitting the trigger button
So, I didn't read the reviews in-depth, as I prefer to go into games mostly blind, but some reviews mentioned, easy combat, and one in particular said new mechanics makes combat easy. I assume that's the mechanic you are talking about.
As for how easy it is to ignore, no idea. But any attack should be voluntary I assume, shouldn't force you to use an attack.
