It's always a positive thing to see regiments/group of players trying themselves in competitive environnements. More than giving a good impression of the 5th (even though I understand it does matter in your eyes), I hope you guys enjoyed yourselves. Taking 2 rounds out of 7 against the reigning champion of last 7v7 and winner of that tournament is good introduction to the competitive scene, no doubt.
If your experience was deemed positive, I can only invite you to sign-up again for the upcoming 8v8 Groupfighting Tournament in early July, that Shadey and I are hosting. We have only one spot left, but we might be able to push the limit to 16 if there is enough interest.
You can find more information
on that thread. Wherever we see you there or at another tournament, have fun!
