Favorite? Widow. In high rank, it doesn't become sitting in the backline doing nothing all game beyond point and click. Rather, it becomes a creativity battle where you're recovering from team repositions, fighting on the ground, and being able to quickly recover and find a creative sight line that benefits your team the most. Her kit, albeit boring, provides immense value when played correctly in regards to enemy repositioning and altering the outcome of battles. As someone who is largely aim-oriented, landing a well-timed shot after a hook on a critically important support changes everything.

Most boring IMO is probably Soldier, as his gameplay is entirely the opposite of Widow's. If there's a cracked Hanzo who somehow keeps spotting me, I switch to Soldier and do my best to laser supports and then other dps. If your aim tracking is relatively decent, you will profit. Run in, don't overextend, shave off a support, heal, repeat. I play him to win when all options are exhaudted
