Visible Fields of Fire Before Placement
Often times I put down a tower in what seems like a key spot to defend the path only to discover that due to the terrain, that looks like it should be out of the way, the tower's ability to fire on the path is greatly impaired. When this happens the tower I placed is virtually useless and I'm out whatever portion of its price isn't refunded when I sell it.
Would it be possible to add indicators during tower placement that shows where the tower's firing arc would be blocked by the terrain?
