I owned all the champions before the BE update and bought the last one about a month before it went live. Since then, I've gone from level 30 to almost to 130 now playing on average 2-3 games a day (actually 5-10 in a day with a few days off in between, but who's counting). Each level I've gotten a champion capsule with at least 2 shards in it (or the rare 1 shard for a newer 6500 champ). 3 shards rerolled is a new champ for FREE just for playing like 10-20 games (depending on your win/loss ratio). Minimum 810 BE value to a capsule, even that gives you a new champ of your choice every 3-5 levels depending on the champion's cost.
TL;DR What in the f*** are you smoking? It's bad. Throw it out.
