"we nerf champions for their strong showing in the lcs"

You might have to explain that one again

id disagree with the line "if everything else fails" thou ... oriana is known for her synergy plays ... she is picked more often into an organised teamcomps that use that synergy as their core power

i think that her power is trully relative to the power of picks that synergize with her

if your team has a j4 you want ori to back the combo up if your team has a sion you can get ori too

but if enemy team has the forsaken azir who will nbever get ballanced propertly since riot doesnt care ... there is nothing to promote ori in here since most of your plays are reliant on guys countered by azir

but when we speak nidaele and others the op is right ... those guys have something about them that makes them always relevant and welcome in any teamcomp

its false for ori thou ... she is a synergy pick picked for teamplay ... not a champion that is less exploitable thus a better pick
