I for one would want to keep this alive, but like you said, there's a lack of communication. I also have just been lacking enthusiam for yugioh recently and have been taking somewhat of a break, and no one ever seemed to be on when I was.
"You all will probably never hear from me again. I did have fun when people were here but I guess I was the only one who felt that way." <-- Nope, I had fun.
"We even won a war against an undefeated team and I wanted to do more wars once we got more members but it doesn't matter now." <---I still never got to duel in a war.
"I apologize again for being a burden and being useless." <--Wait, you were the one who was the least of a burden. You particpated in events most frequently, and attempted to keep the squad alive at least once before.
Not sure if you'll read this, but I guess this is goodbye.
