I recently picked up a new I7 4790K and got some extra free time and I'm looking to get into A3. I have played over 2k hours in A2 mainly Epoch and Wasteland and a bit of Overwatch. So I was looking what server I should start playing either Exile or Epoch/Overpoch. I've heared people saying that Exile is probably the mod that will stand the strongest between the others, why is this? I'm sorry if this could be a repost.

Thanks for the input
