After reading a thread tonight about adding a capture the flag game mode, it got me to thinking about what types of objectives Id like to see added to future maps. Im really into the idea of making it so that who's on offense and who's on defense can switch during the course of a match. Im more into soccer than NFL.
Id like to see them implement maps that include simultaneous objectives. For instance the resistance needs to knock out an objective vital to the security (such as a supply depot, or a communications array) or to kidnap a VIP while the security has a similar objective to attack on the Resistance side of the map. This would allow a winning team to defend as well as attack, adding a new dynamic to the match. This could be a way to end the maps, so that up until this point the game progresses as it does now, with one team attacking and one defending or it could be a complete match in its own right.
As I described on the CTF thread, you could easily have this be one item / person of interest that either team needs to get to their base.

Another thing that could be fun to add would be to have the attacking team have objectives similar to what we're used to (blowing doors, hacking terminals etc), and to include the ability for the defending team to end the match at any point by completing one objective near the attacking teams spawn. (such as destroy their escape boat, or plant a charge killing some leader, etc). This objective would take longer to complete than the attacking teams objective, and the defense would have to complete it before the attackers completed each objective that they needed(after each objectives the attackers complete the defenders would need to replant). I think this could break up the monotony of defending, as well as allowing truly dominant teams being able to end matches without having to run out the clock on defense.

Figured Id create a post instead of just criticizing other peoples ideas for a change, look forward to your feedback
