The problem with witches is that they are just so easy to use. In my last trophy push (to around 2650), I was often 3-starred by armies of 15+ witches. I would not have minded quite so much except that the basic strategy for witches is so easy:
1. Drop a scout or two to set off any traps.
2. Drop all of your witches near an outside edge of the board.
3. Sit back, and watch the carnage unfold.
The frustrating part about witch attacks was not getting 3-starred, it was getting 3-starred by an army that a kindergartener could deploy successfully. I actually love watching a well orchestrated attack that 3-stars my town. I learn to patch holes in my defenses, and pick up attack strategies.
I learned nothing from watching the witch raids.
That said, it is nice to see that almost no one at the top of the leader boards is using all-witch armies. There is a nice mix of troops in the camps of most of the top level players. I am not sure whether this is because they are so costly, or because they simply stop working against near-maxed TH10's.
I would love to hear some of the strategies used by players deploying a few witches in their mix of troops... and I would love to know why heavy gemmers are not creating large armies of witches (I have not done the math on the dollar cost of an all-witch raid).
Admittedly, all of my wizard towers were level 6 in my last push. Getting them all maxed could help quite a bit. Are maxed wizard towers witch kryptonite? 1-hitting those skeletons should make a big difference.
