SYNERGY HEROES

I want to discuss about Synergy Heroes, cause on this site the synergy heroes doesnt came along with Pro scene data, why Franco and Baxia / Fredrin doesnt have synergy? bcs even in high rank match its often to see Franco as roamer if the jungler picked Baxia / Fredrin due to CC of baxia and fredrin have can make Franco 100% accurate hook delivered. And its also happened in other heroes, just like Cici + Melt down Marksman should be considered as Synergy cause of the front to back strategy(example: cici and granger can burst enemies tank before if the enemies roamer came in offside position + if the granger already have malefic roar)
