I hope Relics are overhauled entirely, or at least can be earned from having religious units condemned rather than only through theological combat. In my view it should be the opposite: Apostles/missionaries should by default have a chance on death to make a Relic if they are condemned by a military unit. Theological combat, then, would function as a method of religious offense and defense that avoids giving your opponent free faith and tourism for losing units. Right now it is very simple to stop a religious proselytizer only by declaring war on them and stomping their religious units. This would also have the side effect of making religious victories finally viable in competitive multiplayer, for people who enjoy that.
