We're looking at it for next patch hopefully :) Some thoughts~
We like the "call to arms" that it generates. It's a strong engagement opportunity for the capturing team and we'd like to retain that in some form. Currently, (as you all called out) it's a bit overbearing and ends up slowing action down a lot because players just sweat it out once their afflicted. Want to find that nice middle ground where the capturing team is empowered, but the defending team still has a fighting chance.
Look for changes soon!
