Swimming/diving, it usually has terrible controls. My prime example is Witcher 3, swimming with Geralt feels like steering a freighter while underwater enemies can quickly move in all directions.

Also I generally don't like platforming, but that's just me.

• Parrying/deflecting attacks. It's just so damn satisfying
• Mass Effect's charge attack of the Vanguard class. It turns you into a projectile to punch the socks off an enemy while also recharging one's shield, so it incentivizes you to repeatedly fly in their faces followed by a point-blank headshot. Headbutting heavy mechs with a Krogan in ME3 multiplayer was great too

I love the dashes in Hyper Light Drifter. With precise timing they can be chained, making them not just useful in combat but also to quickly move through areas. Really satisfying.

Yes, communities where people discuss in good faith are so much more pleasant.

I also got the spinning circle at the login screen, and figured out it was because I hadn't verified my email yet.
