3v3 meta question
Hello! Me and my friends are returning to league. being away since season 1 (long long time it seems). We want to focus on 3v3. That being said, after doing research we have found that the meta includes either Jungle (ad bruiser top, AP control mage bot, and jungler) vs support (ad bruiser w/ smite + tanky cc support + ap control mage bot). My question is simply, why? Why not run adc + support instead of the bruiser? Also, What are the benefits of each comp? is one reasonably better than the other? Thank you so much in advance! we appreciate your feedback immensely!
