Likely because the eth defense bonus isn't supposed to be applied a second time when an item is socketed in the cube. It really is kind of a bug, whether you want to view it as one or not.I dont know why people call it ebug.
Actually I like 4 socket eth threshers and GPAs more because they have lower reqs and are quicker, but Larzuk will add 5 respectively 6 sockets to them and not 4, so you have to use the recipe or find one which already has 4. They are too rare to be used for Insight IMO. I make Insight in CVs and RWs with HRs (like Infinity) in the other polearms.
It's not a bug, it's a correction patch that Blizzard made. In the "old days," when you cube-socketed armor/shields/helms, the game would remove the ethereal defense bonus, and it needed fixed. Blizz fixed it, carried the 1 and multiplied the common denominator by PI, then threw in a .999 for good measure. Well not really, but they DID double-apply the eth bonus, making it a "feature" rather than a "bug."
wut is GPAs?
i have a CV insight but str req 210
using guill and duriel shell for boost up the str
wut else u think is good for boost up the mecr str or which gear for him better(just come back to play dont know anythin~.~)
so my CV should make for Insight or Infinity(which way is better)

Threshers and gpas are nice but a lot (i would actually guess 80% or more) prefer cryptic axes, higher avg damage than any other elite polearm, as well as having low str req's (2nd lowest after thresher) and they only have 1 less reach than the highest (ca's have 4 the highest is 5).
But be prepared to pay for a 4os eth ca, or really any eth polearm with 4os.
