so i dont get whats so abd. You realize that you get a time window that grows and shrinks based on the number of Items of power. And they get to attack any where in that time window. But onlyo ne sg can scheduale at at ime. Still has surprise, but also allows people to have real lifes. not a bad idea.
And base raid does not equal arena pvp - half of a base raid would be figuring otu the design of a base. A straight line with a bunch of turetts would be an easy base raid. A twisty turny maze without a map would be a pain, and allow a few 50's to hold of an SG's worth if theyre smart about it.
