My Conclusions:
Rarely does anyone even do it from 50-59 (0/26).
Few people "try" to get Focus items before 65 (31/53 had Focus 0-2).
Necromancers don't care about DMG INC (0/5!, 4 had afflic3-4), no surprise there though.
Most Focus 4+ were bought (6/9), Tmaps (2/9), Adept (1/9).
I have way to much free time I should spend getting AAs.
Doesn't really conclude much since so few people had the ring or better, and most of those were 60+ not the "~55" intended to get the ring. Appears as if people get the ring for the focus, or dont bother because they have better?
Of the 6 people with Step4, 3 had better focus and the other 3 it would of been an upgrade.
I don't think these rings need anything, but after thinking on it some more it giving it a focus effect that's higher than level 4 would make it out of line with stuff you get from grouping at 65 or entry level raiding and it is pretty easy to go back and power through this quest once you hit 65.
You can get Lv5 from Diff maps (well worn beads/poorly polished scepter), not sure where Dmaps are on the raid scale, but i would think that they would be "entry level" aren't they, the gear seems to be tier2-3ish? Other 2 exceptions:
Red Satin Sash(D5) - Tier2
Winged Cloak of the Soothing Night(H5) - Tier1
Almost everything else H5/D5 was from tier4+, so level 4.5 might be "too good", but there are some lv5 drops before then.
