So I played a game just now as Garen with an enemy Caitlyn on the other team. She started channeling her Ace in the hole and targetting me I quickly silence her with my Decisive Strike I do not get hit with Ace in the hole. But no more then 15 seconds later she channels it on my teammate. Is this interaction correct? Is Caitlyn supposed to be refunded the cooldown on Ace in the hole if she's silenced during the channel?

SelflessTeammate1 votesBecause they're just not the same types of abilities, not targetable for single enemy champions or the initial parts of those skills aren't channels. Poppy's is an AoE skill that targets terrain (which actually does go on reduced cooldown if she lets the second part of the ult run out completely, i.e., she doesn't make any swing), Karthus' counts as a global AoE skill (it's kind of unique, but Karthus' ult is easily canceled by external forces and put on full cooldown no matter how it's canceled), and while I have no experience with Fid's ult personally, I know that doesn't make the player target champions, either.
I'm not 100% sure on this, but I believe an exception is made to Vi's ult, which goes on full cooldown even if the target dies, likely because it displaces her as another of its primary effects, and doesn't have a channel. Also, if her target goes untargetable before it can connect, it goes on full cooldown.
In any case, someone like Skarner has the same thing: If their ult starts but doesn't complete the entirety of the channel, however brief (even if Skarner uses one of his ult's quotes), it'll go on a super-reduced cooldown because it didn't complete the channel.
Project omen1 votesProbably because it's a one-target ability meant for execution, whereas the champs you mentioned have channeling ults for more than one target (poppy fiddle aoe, karthus 5 targets). Idk about the others, but if you play Caitlyn, you will see that when you ult, the cooldown timer starts after you fire. If it gets cancelled before that, she gets a reduced cd to "try again". It's like Sion's Q.
Bootleg Gay1 votesSingle target, windup ultimates can be put on a super reduced cooldown if they get interrupted.
Although, only certain champions have been given his interaction, as it gives them more time to be forgiving. If Caitlyn's targets dies before the shot fires, she has a super low cooldown of 5 seconds to try another target. Garen is the same, as it has a good windup animation. If Zed's target dies before his mark is fully applied, his ultimate goes on a super reduced cooldown as well. If Nami dies while channeling her ultimate, it'll be placed on a 10 second cooldown.
