People are giving you pushback because you create a very narrow scenario in which to judge the set, a set which has proven to be quite popular and a lot of people like, and then bash it when it fails to live up to said measure that it was never designed to meet. It gets very old very quickly listening to people constantly bash something you enjoy.
It's been acknowledged many times that Storm Blast is not a fast set, and if that's what you're looking for it's likely not going to be to your liking. This does not mean the set is broken or otherwise in need of help. It just means that in this one niche usage it's not optimal. And that's OK.
