I wasn't aware of which champions you could get from the orbs before picking them, but I have been somewhat disappointed by some of the inclusions on the spooky support orb, roster specifically these inclusions.
Annie, Malphite, Maokai.
Really disappointed that these completely off meta champs came up in the orbs as they are just so outside of the support role and have been for a while now. My fault for not checking really, although I'm not sure where to look for information about which skins you could unlock (I only found the list in an article published today), but frustrating to have champions come up that aren't really supports when you are redeeming an orb for champions in a specific role :(
I mean, you don't see mordekaiser and heimer on the adc orbs.
