I like the objective mechanic because it gives frigates something to do as otherwise they are almost completely obsolete in big fights(except for outliers like Hyperion or Monitor) - I assume that was the goal. The problem is that the objectives themsevles are poorly executed and usually don't actually achieve what they're supposed to.
Take this for example. The two objectives are right next to my fleet so I don't need frigates to take them at all(there is one possible objective configuration -
the diamond one - where the nearest objective is
right in front of your fleet so you end up capturing it even without trying, just by flying over it) Also note how I get screwed and got two Comm Relays - which do nothing for me because I already deployed my entire fleet - while the enemy gets the much more valuable Nav Buoy and Sensor Jammer. Finally the map is quite clearly split in two so both me and the enemy can get our own objectives and call it a day.
Quick and dirty mockup of how I would like objectives to look like. Uneven amount so that there is always one to fight over, out of the way of the main fighting to make frigates more relevant and mirrored so that you don't get screwed by positioning.
I too love when the game let you camp in a corner and cheese the AI /s
If your fleet is stronger then hiding in a corner is not necessary. If your fleet is weaker then it's downright suicidal because your ships don't have anywhere to retreat and will constantly block one another. I don't think camping corners is exploitable, objectives or not.
