The interrupt thing seems cool to me because you can make a dude that isn't all about damage. It also gives speedy weapons added value even against dudes with high DT. I can see a ranger with a speedy short bow being very valuable - so much so, that I might opt for that instead of a might heavy ranger with a gun. This opens up more viable builds and thats a good thing.
our ranger appears to achieve most o' his damage via his animal companion. as such, we has decided that our ranger will be interrupt focused. animal does damage, while our ranger sits back with a fast ranged weapon and concentrates on interrupt. that being said, we would like to have some kinda reliable feedback that shows whether or not interrupts is efficacious.
and seriously, we would like a way to see which foes is suffering debuffs. this is particular important for rangers using marked prey.
HA! Good Fun!
