I love the idea of HQ on 3rd row. It would twist up gbg. I dont worry that a major change in how GBG is done would ruin gbg for all. GVG has changed a lot since FOE started. I remember no auto battle. Major change yet the game lives on.
Limit the number of sectors that can be taken daily. This was done in gvg to level the playing field. Multiple 1stplace in a row should qualify for diamond. Keep the big guilds up and dont force a mediocre guild up for 1 good week.
