I feel they add more to the game. Well, the ones that aren't Red anyway, I'm biased against those
But with Dropzone Commanders space battle game coming up, I was sort of enamored of the way they're rumored to be doing objectives. Basically no one fights in deep space because there's nothing worth fighting over, it all occurs around planets or stations and such.
I'd like to see some objectives that are similar to those, where a ship might have to stay at short range to a designated planet section to provide orbital support, or escort troop landers, or some such. Don't get me wrong, I love Armada and am likely to keep loving it. But I would like to see both more objectives AND more restrictive objectives to discourage Total Party Kill games (totally my personal opinion there).
