Does anyone have/use this skill? Thoughts on it?

I keep wondering if I'm missing some fantastic skill with this one, there are times where I wish I had it mid-match, but it just looks very weak when reading it in text form. Weak may be the wrong word- but unreliable is accurate. As a one point skill it doesn't feel useful enough in terms of potency or effect compared to the other pvp skills, and the fact that even talented with the extra point, it still maxes at 40% chance to add heavy when hit from behind... it just doesn't seem reliable enough to... rely on.

Does anyone have anything nice to say about this skill?
