Honor Capsules (imo) don't actually give enough 'stuff' to incentivize good behavior
This may be a touchy subject but honestly, I feel like Honor Capsules hardly give anything that really urge us to better ourselves. I always do anyway since I know that has a massive impact on win rate and overall team morale but I'd definitely think if Honor Capsules gave actual, meaningful things, Honor level and overall good behavior would be far more appealing.
I know it sounds like I'm just asking for free shit but honestly, maybe Riot would lose out on some sales revenue but player behavior would drastically be improved if they literally "provide enough" of a reason to make us want to improve behavior.
So yeah, I don't need this at all, I just thought that this would do far more good than harm. Well, harm to the players, not harm to Riot's wallets.
EDIT: They could either increase the loot or have something exclusive to Honor rewards in terms of progression. They have two exclusive skins but that's all the way at the very end of Honor 5, something that's "seemingly so far" that it kinda makes us give up in getting it. In order for Honor (or any real) progression to work, we need rewards for the progression itself, not just by reaching the destination.
