Is this try-harding?

Okay, I just finished playing a Poro Mode game (awesome mode, Riot, Santa is gonna give you gifts), using the Alistar/Blitz combo with my brother. The enemy team was a nightmare to deal with in this mode: Zilean, Blitzcrank (I guess we deserved it for picking him as well), Jayce, Ziggs and Thresh. I hate all these champions so much in ARAM... Ours was no better, but we were uncoordinated, while their Thresh/Blitz and Zilean were clearly premade. Anyway, we kept landing poros and summoning the poro king, dodging hooks, as their Jayce got insanely fed and we had to lock him down. No biggie. Then, I dashed from base to theirs (where our king was) and noticed their nexus was exposed. Their team was aced, some of them about to respawn, and only I was full. Being already fed up with their team comp (I hate pulls, I hate poke and I hate a GA every 30 seconds), I just pulverized the minions (I was Ali) and kept auto-attacking their nexus, while the enemy team chased my low health teamates. When they realized what was going on, it was too late. I ulted and ended the game at 16 minutes. Then their Blitz called us tryhards (which is incorrect because if anyone did tryhard, it was me) and I just left the game getting a teamwork (fun fact: not from my brother). I do not flame, and I usually don't care that much about victory, but that teamcomp was super cheese (for me at least) and I just wanted it to end.

If this wasn't tryharding, please tell me what is. And if it was, I am sorry to everyone that played against me :c
