At first, Lunacy Mage was working just fine for me yesterday until I got to Diamond 1 with 3 Stars then started going like 1-8 since then and dropped back down to Diamond 4. Considering how many times I face Paladin and just got wrecked by then, I finally gave up and played Secret Paladin the rest of the day.
I managed to hit Legend for the first time last night after playing all day long.
Ever since then, I lost like 12 times in a row, most of them to Paladin. I hasn't seen any Warrior or even Warlock since I have been in Legend.
I am just glad I don't have to do the Legend grind again. This Standard meta sucks big time.
