Because It was too difficult to know who's trustworthy and who's not. And even if I found and made an alliance, they'd just split up every nomset. This was because of people overplaying the game and not taking it as a game. So I started doing what was done towards me. I started playing between two sides, tried to avoid being nominated almost every DC after reaching f10.
I knew I was in a bad position. I tried to build really strong relationships but I couldnt because of all the premade vs. others thing and the one sided alliance that is going on right now. I was considered a threat by almost everyone in the game and I made it this far, which itself is an accomplishment.
