Customized Rewards for the season to make it more exciting and personal when you receive rewards

I think the new stuff with the rank-symbols would be cool, if the player was able to chose a faction from the beginning. Why would Shurima be higher than Demacia for example. Would be great if you could chose a faction and then get your rewards depending on that chosen faction.

Also, it would be way cooler to personalize your profile with lore based factions.
