Last i checked more honor generates more key shards. Heres the relevant Changes and here is some FAQ that I assume will remain accurate.

Do all my key fragments still drop through Honor? Yes. When we updated Honor last year we decided all key fragments would drop through the new feature. That’s still the case. How do I get key fragments? Get all your key fragments by doing two simple things: Playing games, and avoiding Instant Feedback penalties like chat restrictions and bans. That's it. It's an intentionally low bar, because we want you to get your stuff. You don’t need to be honored by teammates to get keys. Individual honors are connected to other rewards like loading screen flairs. Keys can drop whether you win or drop the game. Key fragments hit while browsing the client or on login. You’ll also get key fragments at checkpoints and level ups. Will I just get keys by idling with the client on? Not just by idling. You need to play games to get key fragments. So for instance, If you spend your Saturday playing games and leave the client on overnight, you might wake up to a nice surprise. If you just boot up your client and don’t play games, you won’t get any key fragments. So, they'll just show up sometimes? Yep. Just like a fed Twitch coming out of stealth.
