You want to know why broders cost extra on SG skins?
Because Riot gave us too many ways to get free skins and now they lose money so have to charge us on something extra. We have chests and capsules and I'm sure some players rather than buying skins wait until they drop something for their favourite champ. Riot is a company and their #1 priority is earning money like every one else, so can you all stop complaining?
