Champion Mastery Chests... Underwhelming Reward?

So, on one of my alternate accounts, I just opened a Champion Mastery Hextech Chest. Remember, those require you to get an S- or higher (or a teammate you're grouped with, but I play solo for the most part).

I opened it with a key forged from 3 Honor key pieces.

Upon opening it, I received...

drumroll

A single ward shard. Nothing else, just a single ward shard.

Now, don't get me wrong, I understand that Riot has to keep free stuff to a minimum, in order to encourage money-flow into the game from end-users, but I feel that something with that many requirements to earn/open should feel like an actual reward, not like I just got a pack of crew-cut socks for Christmas.

Even if it had just included a bit of Orange Essence, it would have been okay, but it just felt completely underwhelming to have to do that much to earn the chest and wait that long to get the key to just get a single shard for a ward that isn't even hard to get.

Is there a bottom-end limit for how much a chest can be worth in terms of Orange Essence? If so, can we get a SLIGHT buff on that value, so that players don't feel so let down in the end?
