Rook main

The most friendly/helpful individuals in siege. They are often chill people who solo queue. Everytime I see one perish due to toxic TKers, a small part of me withers away.

Bandit main: Geez without that armor, that flank would have failed
Rook main: That must be stressful
Bandit main: shut up *shoots Rook main*
Me: prepare for a civil war, simpleton
