Looking at the result, I was quite surprised. But after watching the match, I think Kongdoo Uncia had it coming.
Watching the Battleroyal matches against X6 and Flash Lux, I had a feeling that although Kongdoo Uncia is a good team with players with decent individual skills, they lack synchronized team plays. Most of the team fights they were able to win depended on great individual plays, but when the opponent came at them with well-practiced team strategies, they just got wiped and trickled in one by one. I think this might be due to a fact they have so many new players (3, I believe), so they didn't really have much time to practice team plays yet.
This match went to MY exactly because of that. MY forced Kongdoo to be gathered in a confined space using a widow, and MY went with Reaper, Reinhardt, Zarya, Ana, and Lucio to wipe them all at once. They just did not know how to deal with that. Hopefully, Kongdoo will improve on their team strategies as they play more games with the new roaster.
Interesting. They next face AFB in the BattleRoyal on July 25th so they'll need to iron those quirks out fairly quickly or else it may end up being a repeat of their APEX group match.
