Even with the buff to 15% its still probably the most negligible upgrade in the entire rebellion(even more than Fury of the Unity). This picture was from a three hour game with a maxed out army. The units in the bottom right panel are all the ones I got from RotF. Either scrap the ability or buff it by an extreme amount I am not sure what the best solution to this would be because of the nature of the ability. Sorry guys but the Advent were in my opinion terribly put together. Also I mean no offense to the developers I can understand with such a small team how difficult it can be to balance out some things.
