Since this is a discussion on homebrew games vs. Adventurers league, isn't the treasure given out up to the DM anyway? If the DM wants to grant a ton of items to their players and take the challenge out of the game by making the characters so powerful they never feel danger, then so be it. Adventurers League is a bit lighter on magic items over all, but it is still possible to obtain two uncommon items by level 7. Heck, I have a level five AL character that has a rare item (And could have had two, but there was another player who didn't have any magic items at all.), so it is not that uncommon to see level 7 characters with two or more magic items.
