Frankly, Riot, you should be able to CHOOSE what skin you get out of the Honor 5 capsule
For example, Twitch is Mastery 4 on my account (primarily through ARAM/ARURF/One For All). I have no desire to own Medieval Twitch. By contrast, Warwick is Mastery 7 on my account. He is one of my most-played Champions. I really, really want Grey Warwick.
The fact that I have a 50-50 chance of being completely and utterly screwed over on a once-per-season capsule is a GIANT middle finger. Like, your chance of getting the skin you want isn't even affected by how much you play the champion - a Jungler main who plays a bunch of Warwick could end up with a skin for an ADC that they've literally never played in their life.

EDIT: My solution would be instead of giving players an 'Honor 5 Capsule' that randomly gives you stuff, we should get an Honor 5 Token (a Token that you get once per season for hitting Honor Level 5) that allows you to select either 'Grey Warwick' or 'Medieval Twitch' - the same way you would with Gemstones and Event Tokens.
