I think we're getting a little hyperbolic if we ever sat the objective didn't matter. At the very least the obj compels players to move a certain way.
this is a huge point to stress
back in Warmachine, I had a lot of people say objectives didn't matter because we so rarely won based on objective unless someone was horribly down on attrition and didn't have models to contest points. Similarly, if they got their caster assassinated because the caster was too close too the front, chances are it was because he/she/it needed to throw their weight in order to secure the objectives on the table.
thing is, if it weren't for objectives forcing players' hands games in warmachine would never have played out in any similar way. They're a massive influence on every engagement, even if you don't score a single point from them because they influence how both players have to move/engage
In Armada, it's the exact same thing except, instead of winning outright they can provide an insurmountable lead or completely change the nature of the game (hyperspace assault, fleet ambush, dangerous territory, minefields etc) or both (advanced gunnery)
