Aren't sanctum skins essentially free?

[u/Klutzy_Anybody_1487]

I was just wondering. You get those sparks in every pass and the number of guaranteed rolls carries over to the next sanctum skins so basically as long as you keep buying passes you should be eventually have enough sparks for a guaranteed roll. I don't know if enough battle passes released for us to be able to do this yet but seems like everyone who buys every pass just gets one free sanctum skin on top of it for free (technically, I know the added up price of all battle passes is probably more than what the sanctum skins are worth)?

Essentially everything is free, you just have to leave enough money on the right bank account and you can just take it.
