Direct Hit; how much is "enough"?

[Claire_Pendragon]

Ive heard various people say that DH does have diminishing returns at 1,800 (last patch) though Ive never been given a source to back it up.

Since Ive got no real way to test it, Ill generally aim for 1.8k, and just go crit for the rest anyways, not too big a loss if im wrong.

I'm always curious about these sorts of things and since I'm horrid with math I have to rely on the intelligence of others and personal experience about what works. Since I'm most proficient with smn, but I'm still causal for the most part I'm not sure what I think will weigh heavily but I'll take a top tier smn as a sample. Super summoner is running approximately and rounded around 2K crit, 1800 direct, 1200 det.

I'm guessing crit starts becoming more important than DH at some point, the question is where is the tipping point. (Also that doesnt take in account det). Here is one article I found a while ago by Ver Haad. (Maybe someone who's got a better brain for calculation can give more than me).
