Magic Finding on EA DeadEye - How Long can you Go?

I built an LA Deadeye and acquired a Headhunter. Since tuning for MF, I've dropped from 5.5M DPS to 3.5M. Main questions:

1. How low can you go on DPS?
2. I feel slow until HH kicks in - is that expected?
3. Legion payoffs are lackluster so far. Is it really worthwhile?

Long form:

I realized a great use for LA Deadeye was Magic Find on juiced maps, especially Legion in Cemetery. So I started swapping into MF gear. Most MF builds seem to have Flesh/Flame for Master Surgeon, presumably to sustain Divination Distillate. That's currently outside my budget, but I slapped together some decent Ventors, Goldwyrm, Sadima's etc.

The build feels so much slower and clunkier, except when HH gets rolling. I'm at 224 IIR and 48 IIQ, with 3.7M DPS and barely making my resist caps.

I could go further down this path, dropping my Hyrri's Ire for a MF chest, dropping my Hyrri's Truth for a MF amulet, etc. But I'm starting to feel like a turtle until the HH gets going. Is that really what you have to do in order to have a profitable time grinding Legion Cemetery with scarabs and compasses?

On a related note, I've dropped somewhere around 1 div per map (averaged over a dozen maps), but the big drops (two Brother's Gift) weren't legion drops, and neither were the natural divines. How much is the Legion really worth? It seems to mostly be some Maraketh splinters/stones and a few stacked decks.

Current build. Just swapped Helmets, that was the 2-minute craft and needs to be improved.
