I'm not even sure who in their right mind would think it's a good idea.
"This faction seems to be outnumbering the other 2 significantly..."
"Hmmm... maybe... yes I've got it! We add a mechanic that allows them to take keeps 10 times faster, while also giving a boatload of zerg surfing potential!"
"Brilliant! And maybe we will allow it to respawn in areas they control so that they could have a great chance of getting it instead of forcing them to zerg keeps without it where the smaller number of defenders might have a chance!"
"Amazing! And when they have everything they can then gate camp the other factions making sure to kill all pvp for an hour or so at least!"
"Yes! We've successfully kill- I mean saved pvp!"
