Did they snowball? They played Ekko.
Did they get massively ahead? Were already ahead after picking Ekko.
Did you itemize properly? Tank still works, AD Ekko can work. AP Ekko definetly works.
Did they counterpick you? What doesn't Ekko counter.
Did they have a better comp then you? Nope, they just had Ekko.
and finally, the hardest question of them all...
were they a better player than you? They went negative 0/11/6. Still ended up winning them the game. Thank god he was better than me by playing a champion WHO:
Has 2 gap-closers(E and Ult Travel)
A Slow
% Damage
A Stun
A Zhonyas
Ability to build basically whatever items and still do absurd damage
A Barrier
A overly buffed Self Heal
A speed boost
On hit damage via basic attacks
Did I mention you can't see his W til it forms the bubble and can be cast from his turret out into the middle of mid lane at level 1 and whose E automatically hits you if you are in its absurd range.
A very annoying voice
But no that's ok, he was just better than me because I picked one of the 100 champions who come with!
A knockup
No gap closers
An ult that does the same amount of damage his ult does if i stand still for 3 seconds whereas he can just instantly press R, heal through my ult and one shot me with his.
