T6 for pretty much everything, they already had their push and probably will get more expensive still. Not much money to be made here though, as they are rather high up there to begin with.
But has anyone of you checked out KARKA Shells and Mystic coins yet?! Especially the Karka shells are dirt cheap (2s/piece) and you need 250 for a good Infusion (+5 Agony Resistence + stats) which can ONLY be crafted - so I predict those will go up in a week or two to insane amounts.
Make sure to stuff your pockets before that time
Same applies to Mystic Coins, they have been falling recently - but are on a steady rise again, though - as you only need 20 per Infusion, the profit margin may not be anything close to the Karka shells.
Anyway, thought I'd share!
