Zerg Ultralisk stealth nerf

As can be seen in the patch note discussion of this thread ultralisk splash damage was changed to fix a bug.

This so-called "bug-fix" isn't so much a fix as it is a huge nerf. The splash range was as blizzard intended, but the unit radius +2 from unit center rule got a bit too crazy once they allowed you to target buildings with it. Now they changed it to +2 from the front of the target which fixes the "bug" but effectively nerfs splash range against bigger sized units. Smaller units go largely unaffected. Tanks are also affected, but not as much as they are medium-sized. This last sentence is wrong. See edit on the bottom of this post.

Result?
