I don't exactly remember, but there was definitely a nerf - if not to 40, then it would be 100. I used to be a Boomerang fan in Battles, but the Tier 4 upgrade prices have also been increased (a long time ago, it was cheaper).

If you want to use Boomerangs, you can pick it as your fourth tower, as I have only suggested 3.
