What LoL supports are the most played on Korean servers? Only there

Who is currently the most popular support in Korea?
In League of Legends, everyone on the team has a specific role. In bot lane, you can usually find a shooter and a support. Often, however, instead of the usual ADC, AP carry appears on the bot, and the standard support is replaced with unconventional picks, which are used in this role for various reasons. It has also been known for a long time that the League of Legends meta differs depending on the regions, and the Korean servers are definitely the most characteristic. What is the most often played support there?
Support in Korea
There have been many reports of individual builds or heroes on a given line who started their success in Korea. The players on those servers are really creative and have often set trends that League of Legends fans from other regions have followed.
This time players from the Korean server decided to use Amumu and Heimerdinger for support. Perhaps the first one is not a surprise to many, but compared to other servers, it is difficult to compare the popularity of these picks.
Amumu is doing great in team fights, so players felt it would be a good idea to pick him on support. Teamfights take place really often in ranking matches. Moreover, Amumu is a good counter to another popular support – Yuumi. This is demonstrated often in the professional scene, where Amumu is often picked when the heroine is on the enemy team.
Amumu on support can be built both as a tank and for AP, which allows the hero to adapt to the needs of the team.
Heimerdinger – the second of the discussed champions – probably gained popularity mainly because he is great with catching and more resistant to damage supports. He significantly facilitates the game against supports that must initiate a fight thanks to turrets, and a large poke can effectively discourage the opponent from aggression.
Everfrost is a less popular item but allows you to win about 2% more games. The item serves as a supporting one and can be completed much earlier. The Everfrost + E and turret combo is really strong against the enemies discussed above who need to initiate a fight.
