Wanna know why the game has a shortage of supports? cause Riot only recently started releasing fun supports.
very few interesting mechanics. Sona is neat and has potential but in reality, her playstyle is meh.
Thresh while a strong champ is basically a hook bot.
Pyke is kind of busted but very interesting. A support who focuses on finishing targets with his ultimate to give the gold to both him and his adc.
Yuumi is basically Mina from Dawngate, so yea. hella fun and interesting.
Riot needs to keep releasing supports that change the concept of what it means to be playing support. In most MOBAs that I've played other than League I main support because they make such interesting kits for their supports, but League has all of these boring milk toast supports and that's why no one wants to play the role.
