I’m gonna link a post of mine since we have similar feelings on plague ichor:
The devs said they are also working on a talent tree maybe the Plague Ichor will be a part of it.
Teleportation has been discussed on the forums as well, many seemed to want more options. Or I general teleport to a specific area. Unsure whether or not I read something about it on X being expanded upon. Might look it up later and add a link if I find it.
