Squads are obviusly free to do everything they want to. Rotating is fine, you get more friends and learn to know new foes.
I find sickening people changing side just to get bigger scoring opportunities (read: vulching) and squads changing side when their land is in difficulty, like the Rooks now.
I've found myself and my Knight squad gangbanged and reduced to 2-3 fields for days and even weeks in the last months. But I didnt leave and I'll never leave Knightlandia while surrounded and in deep sh**t. I'm Knight and proud to be it, even outnumbered, vulched or w/o radar due to out-map quake-buffs.
