If I had to guess Karnor's is probably less visited on Blue than Green. You can still find pick up groups for low to mid 50s in Karnors on Green. Therefore Swarmcaller entering the economy more often on Green. There are probably many many Swarmcallers chilling on unused characters on Blue, but just not as many new ones entering the market there.

The main camps in KC are camped most every time I log in on blue ... so that clearly isn't the case

Now this might be the case. The population is smaller, more watered down, and likely full of raiders and a lot of raider alts who aren't going to get excited to go sit in EC trying to sell an item for less than 2k.

UPDATE:

I scrounged up sufficient plat for a Tolans bracer!

Makes sense. I'm on Blue like 5 minutes a year these days so I don't have any data other than speculation from past. You being on Blue I take your word for it.

Grats on saving up for a Tolan's Bracer. Easy way to fill up with tons of arrows.

swarmcallers for 1.5k rarely

enchanters will pay 4-5k easily if they really need one

Level 52 now. Still no luck on tolans bracer … but some day …

As an aside, think it’s possible to trade TStaff for fungi? I have an IFS on my monk Incould use alternately (and I never really play her anymore)

On blue TStaffs sell for around 40k and Fungis sell for around 45k last time i checked. So you should be close trade-wise, unless the market changed again.

like 35 and 38 now

Is Brogg camp typically open in seb on Blue these days?

Hit or miss. Decent number of chanters are parked there.

Kind of surprised. 150 months of Kunark farming.
