Re: Trading Ethereal 4 socket thresher
I don't think I can let this go for 2ist. That's just too low, sorry. If I made a game for even an ohm, it would probably be traded in about 2 mins :/ 2x ist is less than half of the minimal value I could get for the eth thresher.
Rarity has something to do with price, but so does usefulness. Infinity and Insight are some of the most wanted merc runewords in the whole game, and they are harder to find good bases for than runewords like enigma. In fact, almost every character uses them. Thresher is particularly nice because it has low requirements to equip, thus giving a lot more helm and armor options to the merc. You don't have to wait until level 85 (holy crap!) just to use your infinity like you would with a cv. It is also the easiest weapon to reach the highest ias breakpoint with, thus giving you more attacks per second and more leeched life to keep your merc alive. Some elite polearms are just disastrous to use (cryptic axe, looking at you). Thresher > cv by a long shot (not to mention less common).
Due to its usefulness, rarity and high demand, the price is appropriate. But I didn't make up this price - this is the going price for such a weapon, or around this price. All the ethereal elite polearms are NOT priced equally.
If you don't care what elite polearm you get, then by all means, get an eth cv. They are cheaper. But if you don't want to waste your 2x Ber and other higher runes on a junky base, then you should get an eth thresher. Why work so hard to get 2x Ber just to put them in a cv for? Seems like such a waste...
For merc runewords, Thresher and Giant Thresher are what you want to use. In the same way you'd want an Archon Plate to make an Enigma, Chains of Honor or Fortitude (for the 0 speed and stamina penalty, and awesome defense vs. requirement ratio), you'll want a Thresher to make an Infinity or Insight for similar reasons (attacks per second, low requirements, etc.). It's really that clear and simple.
