Ranked Division Rewards idea

Something I noticed in ranked is that many people become very complacent with being <insert rank> Division V.

Even if you play perfectly, it'll take take around 30+ games to reach the next tier which is what many consider to be the next real reward.

I was thinking that it may be a good idea to add some kind of division rewards as you climb the ladder. Maybe something related crafting like a Chest and Key when you reach a new division. The rewards are then considered "acquired" so you'll have to go to the next division to get the next reward.

Even if you end up demoting, you were at least rewarded something for putting in the effort to reach that division.

It could also implement some concepts from the leveling system like rewards being a lot more simple at lower ranks so players don't feel like they're missing out on something and to prevent people from purposefully starting at lower ranks.

The ranked system is tedious to begin with and probably somewhat outdated. But completely reworking it is a large project and I feel like implementing smaller things like this would be beneficial for the time being.

I feel like there's a lot of ways a progressive ranked rewards system could be added. What are your thoughts?
