More information is needed in-game. We can't just have players relying on outside sources for info but things that seem likely need to be clarified.
For instance, before they changed hurricane, there was no indication that it did not proc on-hit effects. Of course one would've expected that it did at the time and been building it as so.
There are still currently a reasonable amount of things that need sufficient explanation, warmogs for example is one. Those who read the patch notes know it is based on missing HP, but in-game description isn't clear about that.
