OH YEA! I'm just loving this!

I just found out from a different forum thread that the Spread Your Wings skill, when activated, gives you another skill called Flight, which allows you to leap around similar to Tactical retreat.
Where is that mentioned? Why do I have to find these things in a frigging forum? Why isn't that in the game?
I thought SYW only lets you 'float' above surfaces, that's it.
If you look at Medusa Head, it says it also gives you the Petrifying Visage skill. But this one says nothing about an additional skill. Why the inconsistency and hiding info ?
SERIOUSLY, I'M ASKING THE DEVS, WHY THE ARE YOU HIDING THESE THINGS FROM THE PLAYER?!
I've made so many wrong decisions because of the bad skill tooltip info.

(forgive the outburst, i'm sure it'll pass... until the next one)
