Ironfoe proc discussion

Greetz guys,
I'm bearer of the mighty Ironfoe and wanted to share my thoughts with you guys. Maybe some of you agree with me or can confirm some mechanics.
First I want to let you know the proc chance feels mediocre to terrible. For example: it seems to be on par with Hand of Justice, which has a 2% chance.
Does it scale with hit chance? Fighting lower level mobs that don't make me miss that much, I get a good amount of procs.
In addition it might have an internal cooldown, because It never chain-proced multiple times, but I got it immediatly after on the next autohit.
An annoying side effect is when using Heroic Strike/Cleave and get a proc, the rage consumption is doubled, but the spell effect is only applied to the first hit.
For a best-in-slot weapon until Ahn Quiraji/Naxxramas I expect a little bit more. Don't get me wrong, it's not bad overall, but not that cookie cutter that I expected.
