Yes, that's about correct. If you think of it that way you'll generally draw the right conclusions.

It does, but there are some diminishing returns. For example (all totally made up numbers) if in a given situation Trapping alone would give you 50 damage and AO alone would give you 20 damage, the two together might give you 60 damage.

That being said, if you're picking trapping and you're already committing to that kind of gearing strategy you might as well pick up AO too.

I saw no difference with my Cloud Ranger taking it.

Does it require heavy weapons?

Does it make your weapons harder to parry?

It's not broken. Yes, it requires heavy weapons. It adds damage to every hit with them.

But if you're expecting an edge to turn mangles into devastates you're way overestimating it.

Does it have any affect on Parry?

Don't remember.
