This is like a slap in the face every time I read it. "Oh, to be honest, I think this will get repetitive after a while." Of course it will become repetitive! Just like every other multiplayer game on the interwebz. Because there is no infinite content (yet).
But at least it will be more dynamic than TDM or DM or CTF. Because there is not only one same objective all the time, but also dynamic ones which vary between games. After a while you'll most likely have seen them all as well, but it will take much longer than "Take this flag. It waits here and will always do" or "Kill this guy. He will respawn here, here, here or here. Take this UAV so you see where he is."
I wonder how a more symmetrical mode is less repetitive? I mean ... it's the same on both sides then, isn't it? Which reduced the content by 50% and thus - correct me if I'm wrong - increases the repetition by 100%.
