If you already had all champs you dont need champion shards, since you already can buy them with IP, then:
-you would be able to change champions shard/essence into cosmetic essence.
-If you keep gaining shards with all champs you cannot fuse 3 of them into nothing,
the system prevent this and show an error pop up.
-There should be bundles for buying Keys and chest x 2 to 10.
-The system needs adjust, the system tend to release several repeated skins,
-I got like 6 Nocturne eternum.
-I got like 4 scuba gragas
- got like 3 warring tryndas.
-3 gragas... etc.
Then the system started to release a lot of repeated champion content,
I got like 6 different WW skins, 6 Trynda skins, 4 blitz,
then several other champions as Velkoz didnt appeared at all.
All this examples were using like 80 chest to test.
I got 2 Ultimates, which both were ezreal.
like 10 legendaries, which mostly were repeated skins, 3 nocturnes, 3 jannas, 1 cho gath,
1 Veigar, etc.
BTW, can we remove the refresh on the shop?
If you use the shop, which got a new refresh effect (since several months ago),
it makes a delay when you buy something, then if you sort the items to buy and buy anything,
the resfresh remove the filter, so you must calibrate it again.
With a few tunning this system will be nice.
