The only two heroes that arent playable in 1v1. Lets not leave em out of the fun, guys!

After extensive playtesting with those two heroes, we found that the matches would draw at an exceedingly high rate.

We have future plans for 1v1 (as well as 3v3) to reduce draws and hopefully that will allow for the return of Mercy and Lucio to the mode.

Since the time of this post, there was a "Limited Duel" mode released in May 2017 which played the 1v1 elimination ruleset except each player would pick from one of three possible heroes that was randomly selected, including Mercy and Lucio. However this mode no longer shows up in active arcade matchmaking rotations and has since returned to Mystery Duel.
