Every champion you mentioned here is a damage dealer. Damage dealers sit outside of "viability" because damage is ALWAYS good. Even if Orianna can bring massive utility and great stuff to a team, if a champ can 1v5 and win everytime, Orianna is useless in comparison. I dont like how you basically crossed out any notion of my idea being correct because you based it, solely off of Tourney play and damage levels.

Synergy means the capacity something has to work in tandem with something. Orianna and J4 have 100% synergy because Orianna can pull everyone into J4's ult, if perfectly executed, massive damage will be inflicted. This is Competitive team comp;

J4

Orianna

Miss Fortune

Sona

Riven

They all synergize with each other in some way, and in teamfights can pull off insane things. Since you said you dont understand exactly what "Synergy" means, Im not really counting your opinion as your judging something without a total understanding of it.
