While it’s good to have something alternative to do, side objectives often have irritating impact on the enemy team. Let’s look at the capturable-spawn example. In old ET only 2 classes were capable of “capturing” enemy spawn: CvOps and Engineer, what’s more - both used different ways of doing that, tactically: dynamite gives enemies almost 30 sec to react, while only CvOps was capable of almost instant spawn-“capture”. While everyone can - at no class-choice costs - destroy enemy spawn, there seems to be a little bit too much of that business around. Losing the spawn makes ppl angry, capture-loss-capture-loss… can go on forever… Is that fun? Well somewhat. Yet old ET way was, in my opinion, better.
From the spawn forth to the objective - side objective: which calls you? What side objectives would you like to see in the Unannounced? What would their impact on the gameplay be?
enjoy your creativity! And have a good day.
