Untargetability frames.
The untargetability frame "mechanic" (if it can be even called a mechanic at all) is the worst thing League could ever introduce back in the day. Why is it becoming even more popular now? Out of the 10 most recent champions/reworks released, 5 of them have this so called "mechanic" somewhere in their kit.
While it can indeed be a source of potential outplays, randomness also comes to play, and randomness doesn't define skill. A spell with this "mechanic", apart from its actual usefulness, also applies a certain amount of pressure on the enemy and forces them not to use their tools waiting for you to use your untargetability spell. The most frustrating this is that there is no actual punishment for incorrectly using an untargetability frame spell, as it is going to do what it always does anyway. But anyone else is punished for using a spell on that champion at the wrong moment.
I'm not saying to remove the "mechanic" from the champions who have it (even if removing it from the likes of Kled, Xayah and Kayn would be very healthy for the game), but stop abusing it now. Thanks.
P.s Mobility creep isn't a good thing too.
Telegraphed. How can you possibly tell me with a straight face there's an element of randomness to his Mount/Dismount mechanic?
Basically Yi. As a carry, her Ultimate is her main defensive tool; she wouldn't blow it out of random especially since it's not actually that powerful. Unless of course you're bad and the Xayahs you are playing against are also bad.
Also Yi. Actually, more Zed. Unless Zed's predictable Ultimate is also treasonous for you.
