[2020] If Servitors Get Frozen They Shouldn't Be Able to Immune Any Enemies

This concept baffles me beyond explanation. If a servitor gets frozen while "Immuning" a group of adds then the immune tether should immediately cease, end of story. So annoying to be left with a frozen Servitor or sometimes even an entire add group of frozen enemies that remain immune for a period of time. Freezing an enemy should end all effects they have on the surrounding area; good and bad. This could also include Wizard Smoke and Psion Boosts.
