I'm wondering if I'm misunderstanding the usefulness of stealth tactics in XCOM 2, specifically in missions where you start concealed, have to cross a map in a limited number of turns, and contend with multiple groups of hostiles hiding and patrolling everywhere (which FTR pretty much sums up every mission I've done so far).
If I have limited turns to get to the objective, that seems to imply at least one of my squaddies should make haste towards it, and I shouldnt get tied up in combat (Maybe I'm wrong about this, and there are different strategies for VIPs vs. bombs, crates, etc.).
But, inevitably I trigger alarms whenever I interact with the objective, and even if I get the objective successfully, I'm usually tasked with eliminating all hostiles, which are inconveniently all around the objective, and raining vengeance upon whatever poor soul I tasked with objective duty.
I've been scraping my way out of these missions, usually with at least one Gravely Wounded soldier, so I know they can be done. What I'm asking is what strategy should I be taking here, in general?
Should I be sneaky and avoid early conflict, preparing for an onslaught at the objective? (When I do this, I usually get overwhelmed by those onslaughts if I'm not perfectly positioned)
Or should I be taking out enemies as I encounter them, while still progressing towards the objective, so the mayhem is spread out a little more and the encounters are with smaller groups of enemies? (When I do this, I usually end up getting stalled by early combat and missing the objective, or sacrificing a squad member to get it done just in time).
