Your sarcasm is 10/10. And actually all of these things do take skill. Not because they are hard button combos, but because they take manipulation of your environment. They are a combination of map knowledge, maneuverability, and player prediction to get to just the right place to secure the kill. A firebolt, on the other hand, can be easily placed anywhere without needing to know how your opponent will react, because there is no consequence if the opponent dodges. If an opponent dodges your shoulder charge or see you coming too soon, you are dead. If you shadestep in the wrong circumstance, you are dead. If you whif your grenade, you just whif your grenade. You threw it around the corner, so it's not like you're being shot, but your grenade is so powerful that the whole room had to panic because if it even ticked them, they will be one shot from death. Even a lightning grenade only does 122 damage if you avoid the second pulse, and most do.
