Less Grand Arena. More Guild Events (TB/TW)
I am curious to know what percentage of players actually actively take part in Grand Arena. I don't like it myself. I'm in the category of players that will set a Defense and pay little to no attention to the offensive phases. I mainly use Grand Arena for testing defensive squad theories for TW.
I would much rather have more Territory Battles and Territory Wars that involve the entire guild than these constant personal Grand Arena events.
