Not happy with 4 perks? Try 6 instead!
Two addons from wraith give you basically a 6 perk game.
All seeing spirit is a better surveillance
Blind warriors gives survivors the sloppy butcher effect after a unclock attack.
You basically can have 6 perks and with the new wraith changes you don't need the windstorm addons really anymore :D

I still like to use windstorm so that I can zoooooom around the map fast
