I tried my hardest... I got +300 from my starting position... it still wasn't enough... ;_;
That's why Splatoon is a team-based shooter. You could have the highest score in a match between both teams and still your team can lose. Cooperation on the field is key.
And the disconnects well... blame bad internet connections. Although I will admit the lag was probably the funniest parts of any game, especially Splatfests.
I remember during Pirate v. Ninja Splatfest people were "warping" around all over the place, bad internet connections were the culprits. I was on the Pirate side and it really felt like we were fighting disappearing ninjas during the matches.
