Good for two stars, worthless for three starring decent bases. Splash defenses are not "worthless", it's a huge jump to max wizard towers at TH8 and if you space them properly you can make the timing with their heals/giant bombs a nightmare. Considering that most TH8s haven't figured out that 39 is a much better number of hogs than 30, the WT killing a couple more hogs can end their raid early.
