Skitterbots' profane proxy curse auras do not apply some stats

"

Enemies you Curse are Hindered, with 15% reduced Movement Speed

This stat, and possibly stats similar to it, does not work with a profane proxy aura from a skitterbot.

The same stat does work with a blasphemy aura from a spell totem, so it's demonstrably contained in the skill, not only checked on the player. This seems correct, as curses from your skills have your stats. This should be the case even with profane proxy per Mark.

Maybe blasphemy support got smarter at some point (curse reworks/cursed ground support?) and profane proxy didn't?
