My Fault??

I have gotten bitched at on a whole bunch of my games because it was manual deploy, and trench. They would deploy everything on one spot while I spread my men out, and proceeded to decimate them because their men were trapped, and somehow this is MY fault because they just didn't notice it was trench when they clicked join game. Also I keep getting bitched at, cause I am dominating a game on trench setting, but since I can't just advance across the board, the game continues for several more rounds, and somehow again this is my fault?? Is anyone else getting bitched at for this or is it just me?
