If I have learned anything about being a runner it's all about mind games
Mine games are key. this is a key strategy to escaping the hunter and saving other teammates, this works best for Controls since they are able to use Slow bolts and Stun bolts, and in worse case scenarios, Degenerate bolts.
Using stun caltrops on the edge of a cliff after you have climbed it can really save you and put a lot of distance between you and the hunter since it would send the hunter back to the bottom of the cliff.
Bushes are also useful for hiding as mentioned in tutorial area, but you can evolve that with blind caltrops. if the hunter is near you and you are not sure weather he has saw you or not, drop a blind caltrop and if you can spare it, reveal bolt, and make a swift escape while they are unable to see.
I learned a new trick recently which works with any class, but works best with control. I used the map edge wall and clinged to it while being chased, when the hunter got too close to the edge, I hit them with a stun bolt tier 2 and knocked him off the edge when I climbed back up. this requires precision and timing to be able to pull this off
Well I hope these advanced tips helped, give it a thumbs up if it did!
