You're partly right, but to be honest there's a misconception, in my opinion, where if you play stealth, you always have to play stealth.Speed is the largest disadvantage. In a game revolving around every 7 days a horde will happen time is a resource. If you are going slower to clear POIs and loot then it's a disadvantage and IMO the largest one though I readily admit trigger zones is a strong contender for the top spot, though I will also agree that the armor increased it's viability I also must say I strongly disagree with the way armor was done in the game.
That's not how I play. I only use stealth where I can get a clear advantage.
One trick to speed up things is to run a greater number of "previous tier" POIs instead of the bigger ones.
You can easily speed-run Tier 2/3 POIs with a good knife or machete and a pistol if you're well spec-ed into them.
You can alternate between stealth gameplay and assassin's "havoc knife-storm brute force" non-stealth gameplay.
So, in that respect, auto triggers are on the top of the list in my opinion.
