Just hit legend for the first time in Wild after taking a 2 year break from the game. I know its nothing special, but after always getting to rank 3-1 in the old stnadard format before the diamond, plat. format. Its nice to finally hit it after being gone for so long. Played alot of Reno/odd lock, pirate warrior, and ignite mage to get it.
Resetting the ranking every month is too often imo. There should be at least 4 seasons - or 6. 2 to 3 months time to rank up. That's better than busting your gut trying to grind it all up in one month.
This is my take as a casually, competitive, long-time PWNER.
