Perma nesting is one of the most stupid mechanics that has ever been implemented in CM history. The function of an entire hive caste, the sentinels, was to guard hosts.
You remove the possibility of marines to commit suicide \ escape and instead of compensating for this huge nerf, you do absolutely nothing of the same level in order to balance the game.
"Oh, but we slightly nerfed carriers and egg sniping!"
Nothing has changed at all. If you are stunned and a carrier is close to you, it's over, you will be hugged and probably dragged away to be nested while still unconscious, and if you wake in time a tackle will do the work. Egg sniping was in the first place supposed to be nerfed because it was a completely obnoxious mechanic.
At least when they removed hugger combat and cloning they looked for alternatives, such as defibrillators and xenos buffs. This is one of the most cancerous updates we've ever had and shows that CM is decaying development-wise.
