Not enough chests

In Heroes of the Storm, I feel like I’m having less chests than I should be having. Right now, I just leveled up my Varian to level 2, finished my 3 tavern brawl games and got to level 100, which should be 3 chests, but instead I got 2. Is this normal?

Getting Varian to level 2 and reaching level 100 give you the same reward. You can’t reach level 100 without leveling up Varian to 2 so that’s only 1 chest.
