I think the devs should only do 48 hour wars. Take out all the other time lengths. You want that equipment, you should damn well have to earn it.
I've never really seen any triumph comebacks in the last 2 hours there usually determined in a half hour or so.. unless you love running up the scorecard out car be cut from 2 hours
But I think the Devs want that we pay money for xTals wich isn't necessary for 1h wars so I think they won't change
