Are the new leveling capsules guaranteed to give you a shard for a champion you don't own?

Because I'm a little concerned as to the ease of earning new champions, otherwise since:

• You're removing end-of-game currency.
• You're removing champion shard rerolling.
• You're reducing the amount of essence you get from disenchanting (from the current best-case of 325).

Assuming only one shard per level, it's going to take 24 levels (minimum - i.e. you get a 6300 shard every time) to get enough disenchant essence to buy a new champion. I know you mentioned we're gonna get a bit of Blue Essence in the chest too, but I don't see it being enough to actually redeem the shard...

The only ways I can foresee this being improved is (a) more than one shard per capsule or (b) the capsule is guaranteed to be a champion you don't own (unless you own them all), meaning it'd just take one level-up after a new champion release.
