Damage done to troops out with NS is minimal, most of the damage goes to troops home, and yes Elites are very resistant to NS. I think the move away from deep chaining is bad, and even with deep chaining you couldn't really touch off because of cycling acres, you usually always had enough to avoid desertions if you built incoming acres. I'd like deep chaining and the ability to counter off back. Plus if there was a way to actually touch offence there would be less need of deep chains.
I disliked the old system(post removal of razes in war) because it just turned everything into a massive slugfest that removed tactical options. And I like the new system even less. Instead of making everything more softcore why not give respawning provinces back a non-trivial portion of the resources peak they had 48 hours prior to getting killed(something like a 20% respawn fee), and they respawn in eowcf.
As a consequence it would also add more acres to the game whenever a province dies dies.
