It it's spending most of the time on my desk because I'm coding or searching offsets, then I turn it off because it will find it's way crashing onto my floor
I've always played it with off it feels like an extra form of stress when you're playing that doesn't motivate me in game. You're under attack, the screen is already red and you have damage indicators I don't need my controller to remind me how bad I'm doing lol.
Plus I think it helps extend the battery life so I don't have to charge it as much. On the other hand it might be trauma from using the n64 rumble pack and constantly changing out batteries...
