I downloaded the game again after a 7 month sabbatical this weekend. Declared my one man faction about 5 times. Used a few health packs (8 total) and was top 2500 by the time I deleted the app again on Sunday.
I think my stats were 60m attack/ 40m defense and I was matched up against some pretty even teams. Once past the DL, I always had a target.
My point - scores are skewed, participation is terrible, and too much tap/tap/tap to even entertain coming back.....
