A WB will beat up feathers pretty good, however I have never observed that the flight characteristics of the arrow changed that much. Your fletching just looks like they had a tangle with a lawnmower.
The Blazers are a good vane for sure, I have shot them on my hunting arrows for 3 or 4 years. There are others as well that have a similar profile and weight as the Blazers that will do equally as well.
Shooting a WB with vanes I would also try to stick to either a harder material (Blazers) or one that holds it's shape very well (flex fletch). I have seen too many guys with Duravanes that get all wrinkled up after being shot through the WB for awhile.
