Wow, according to how people talk, it sounds like every single enemy in the game got overguard and became immune to CC.
The majority of enemies don't have it and are as susceptible to CC as they have always been. How enjoyable is the game really if you can CC every single enemy in the game to a complete standstill with Gloom, Molecular Prime, Breach Surge or something similar? It becomes a snoozefest. If you go into bleedout as soon as an Eximus sneezes at you, that's on you.
The new Eximus units are here to stay, and they are way more manageable than the old energy leeches who instantly drained your entire energy as soon as they were in range on Steel Path.
