Radius is what makes it good
otherwise it'd be shit
Its a rare and somewhat expensive item, it is fine as is...
Just because it is rare and expensive does not make it balanced in any way. If you can one shot someone coming down the stairs before they even get to where the explosion occurs, that can literally make a base unraidable.
People are getting killed through walls, the range is stupidly large and does deserve a massive nerf
