Well, it happened boys. I just saw Element Mystic dunk on Team South Korea 3-0 in their show match. Most of the maps were relatively close, but neither Jehong or Tobi really had the impact they needed to have while forced to be on Mercy.
This actually gives a huge advantage to Team USA who have a god Mercy on their team along with a very solid flex support since Lucio is likely to be the one to sit out. I'm not liking this Mercy patch, insane picks and mistakes are erased at the press of a button and if she ults she can even allow you to recover from two picks, a situation that happened quite a few times in this match.
All of this is on top of seeing Jehong and Tobi being forced onto a hero that's 1. Boring to watch and 2. requires much much more skill to counter play. This leads to situations where teams with the better Mercy just win by attrition, and victory is almost solely based on who kills the enemy Mercy first...if she hasn't ulted already.
With this match as another great example, I already know I'm not going to enjoy watching the OWC if this isa the iteration of Mercy we get to watch them play with.
