There have been no changes to Skeleton Soldiers on kToS.
I have to say, just because that page says summoners use soldiers over on kToS, doesn’t mean they do. It also doesn’t mean they’re right. I already had multiple summoners come over from kToS to ask me questions on my build, so you should probably just stick with the facts presented, unless they can come forth and explain why soldiers are better. I can only explain why archers are better in every way.
I also have no idea why they would use Disinter. It is worthless, and even more worthless if they got soldiers instead of archers. I don’t think this build knows what it’s doing.
