Seoul Dynasty has announced the immediate retirement of main tank, Chan-hyung “Fissure” Baek.

Fissure is known for his Winston and Reinhardt play, and was one of the stars of the Overwatch League’s inaugural season. He was a runner-up for the MVP award, losing out only to Bang “JJonak” Seong-hyun.

But more often than not, he’s known as the most handsome, best main tank, greatest in the world.

Fissure’s retirement follows a lengthy tweet posted two days ago, in which he discussed burnout and the heavy mental strain he’s been experiencing. In the tweet, Fissure said he might be taking a break for the rest of stage 3, or take a complete break from Overwatch.

Fissure is not the first pro to suddenly retire from the Overwatch League after experiencing burnout. Earlier this season, Dallas Fuel DPS, Hyeon “EFFECT” Hwang also retired citing mental health concerns.
