Well, this is a record for me... making it to Gold I. I posted a couple of days ago about investing in a couple of legendaries and that has made the difference between Gold III or Silver I and Gold I.
So that's an additional 8 to 10 loot boxes. If i can repeat this for maybe another 5 or so seasons, then it would be worth it. Hope the rewards will be good... just a few hours more to go.
Also, this will be the first end of season rewards since the change to loot boxes instead of cards. Maybe some orbs or packs instead?
Made it to level I too but I'm on level 3 summoners. Gets pretty hard to get to Diamond for me as well.
