Preemptive Strike! How to fix Guild Wars & Arena!
It's very possible Gree has beat me to the punch on this, but I firmly believe we need a pop up screen at the beginning of the war to choose a name & 6 armors that are then locked for the 3 day war. (1 armor per knight) this forces smart choice of Main knight armor.
I can only pray they are tiering points above the LvL.100 range for Guild Wars. If they are doing this, they will surely apply the same theory to the Arena. We should also have a number added to our icon showing our total war points earned from here on out & use this number to match you w/ arena opponents.
