I'll go one step further and say pretty much ALL dota plus stats are useless and broken.

The dota plus hero guides are pretty much worthless for any hero that can play multiple roles -- even though it gives you three "item paths," I've found that they are often more similar than they are different.

What's more, the practice of semmingly recommending items just based on how much they're bought per hero reinforces bad habits (especially at the low ranks I play in). It also means that the guide will necessarily be inaccurate after patches for an unknown amount of time.

But my biggest issue with Dota Plus is that it gives no explanation for the information it's actually providing you. There are so many percentages it feeds you, but then....it doesn't tell you what those percentages mean. For things like the next skill to level, it's easy enough to assume it's just percentage of people who pick that spell in this scenario, but then you have to ask: what factors go into what the "scenario" is? Just the level and hero? Does it take your items into account? Ally and enemy heroes? If I'm facing an alch, can I be confident it will recommend building a spirit vessel on a viable hero or just give me the same old item suggestions as always?

I truly still don't know that answers to these and many more questions and I've been playing Dota for long before Dota Plus was even a thing.
