Not sure what you mean by the last line there, but if you are saying LW Red's Tracer is a problem, I think I have to disagree. Nenne is one of the best Tracers and has been carrying LW Red all the way to the top in the Challengers last season.
To be fair, I have not watched this match yet, so it might be true that he did not perform well in this match. I only watched the Nepal map for the match, and it seems like LW's main problem for that map was sticking to PharMercy comp when it clearly was not working out. ROX rushed into the LW ground units with full force, and since PharMercy was up in the sky not able to fully participate in those team fights, LW was simply out-numbered every time.
