That idea is to
Currently, planets can flip in less than a day, if I recall the system correctly. Each eight-ish hour attack cycle resolves planetary ownership; leave for a week and you can come back to find that the borders of a three hundred light year interstellar super-battleground have completely changed. Among other issues, this lends a very real issue of perceived impermanence for any given capture or successful defense – who cares about capturing/defending these planets if the attackers/defenders can just flip things back the other way before the day is out?
Instead…what if it was a combination of two complete weeks, IRL time, of play that decided the ownership of any given planet currently being contested? Planet flips would be drastically reduced…and as a consequence, winning or losing any given fight would be much more important. Borders would change much more slowly, but that very slowness lends a sense of actual, tangible victory to having accomplished something for your choice of House/Clan. The much slower cadence of planet-flipping would also allow Piranha to, possibly, offer more faction-wide bonuses for doing well on offense/defense/controlling more planets, as the much more stable borders would be a lot less prone to abuse and wild variance in any given timeframe.
There’s a lot to be said about such an idea, really. Take the Tukayyid tournament method of giving a planet hundreds of control points to capture, rather than just a few dozen. You could (hopefully, ideally) even introduce a new game mode for Faction Play – use Invasion while a planet is new and the defenders control the majority of hardpoints, but after a certain number of points have been captured by the attackers (“securing a beachhead”), the game switches to the new Siege game mode. Basically, an upscaled nuAssault game mode where both teams have bases to attack/defend, or possibly a less-ridiculously-bad version of Domination – representing the shift of the planetary war from trying to prevent invaders from making planetfall (Invasion) to trying to claim/defend different resources and strategically significant points on the planet (Siege), which would probably require new maps (and thus won’t happen) but could be used to eliminate the severe chokepoint-y issues I keep hearing FW nutters complaining about.
Or they could not do that – the basic idea of massively lengthening the war for any given planet is really pretty easy to implement. People would have to work, and hard, to take their planets, and Piranha would be in a much better place to reward that work. Anyone figure that might be better than a half-dozen random skirmishes deciding the fate of entire worlds?
