I think I'd be much more in favor of a sudden death mechanic than a straight time limit... say after 45 Min, the next point wins. It doesn't actually restrict sniping matches, but it saves spectators from watching a 1 - 1 score crawl all the way to 5 - 4.
I quite like this. There's something similar that happens at the end of a fencing match (the only sport I really know anything about).
A 15 point match is divided into 3 three-minute periods. If at the end of the third period the score is tied, then a coin is flipped. That coin decides priority: 1 additional minute is given and, if no points are scored during that time, the fencer with priority wins.
So maybe something similar could work here. Something like the following:
Game Time: 45 minutes. Alert players to the remaining time at the 20 minute mark and every 5 minutes thereafter. After 45 minutes, the team that is currently ahead wins. In the case of a tie, the timer is extended by 5-10 minutes, with a team gaining priority as determined by a coin toss. If no tie-breaking kill occurs during that time, the team with priority is declared the winner.This has the effect of making the team without priority being forced to make a play to force an engagement. It also means that teams who are behind may also force engagements to attempt to tie up and/or win the game, which adds excitement to the end-game.
Thoughts?
