1. take caps off and converse like an adult and not a child.
2. Riot aint got no time for that lol.

First, I highly doubt you're only ever getting Teemo Champion Shards - getting multiple shards of the same Champion in a row is hilariously unlikely since there's more than one-hundred and ten Champions in the game.

Second, even if you do only seem to get Teemo Champion Shards, there's a crafting operation you can do - Combine 3 Champion Shards => Random Champion Permanent.

Why dont you save a little longer and buy a full champ, not champ shards?

It is random. Sometimes with random stuff you get the short end of the stick. Its free anyways, so it is better than nothing.
