Suggestion: You should get a golden lootbox (guaranteed legendary) every 69 levels

Not sure if this has already been suggested but I think this would be a nice addition to the game. I thought of this idea after reading a reddit post about it. I'm not sure if it has been posted before, though. Sometimes leveling up can feel really slow and it would be nice to have little benchmarks to look forward to aside from the karma of reposting this after every OW session that I quit because no one protected me. There could also be an epic lootbox (guaranteed to contain a knockoff repost of this repost) every 25 levels or so.
