I was not able to find the after-patch-purpose of Purge Crafters.
Are they nonrelevant now?
That would be a shame since i considered them to be a long-term motivation to trigger Purges and trade.
So far i don’t really see any improvement from the last patch for Players on the old map, either with or without the additional recipes from IoS.
But erasing individual skills/recipes from local T4-Crafters on the Map and the bonuses of purge-Thralls would just feel like a huge content-cut (to me).
But maybe i am at least partly wrong and there is indeed still a purpose justifying the effort to catch purge-crafters?
