Hextech Crafting - How about this?

Hey guys, I posted this discussion before in PBE Board but someone told me to post in NA Board for more visibility, so here I am. I know it's been a long time since hextech crafting released, the idea of rerolling 3 shards to get a permanent champ/skin is awesome, but the results are not always good. So what happen if rerolling can give you a permanent champ/skin shard instead of unlocking them right away? That way we can choose to unlock the shards or disenchant them into essences. This is just my personal thought that i think it will improve hextech crafting close to perfection. Some might not agree, but I think this is will make hextech crafting more fun. What do you guys think?

Plz upvote this post if you like the idea so more people can see. :)
