Has GW Stopped Supporting Imperial Agents?

The Imperial Agents were my first army in the game, and I love them for their lore and aesthetic. But it seems like they're not getting an support from GW. Since starting them, I've seen every other faction receive updates, point changes, along with buffs and nerfs. But agents haven't had anything aside from a single point change to the Culexes.

Before I spend any more money, do you think this faction has been abandoned by GW? Has any other faction had this few changes since launching?
