I got a chance to use forsaken archer.
thoughts:
-she builds very much like valkyrie might, in terms of items.
-her snare is great for ganks
-split shot should never be touched, go stats instead.
-skeletons are amazing early (especially if you're good at last hitting)
-her ult is ok early, but the problem is trying to hit more then one person with arrows is difficult.
tensei and i both had thought originally that she could be a potential jungler...the answer to this is yes and no.
if you get something like helm of black legion or the agi shield you can...but just with the skeletons you cannot. creeps don't attack the skeletons they always go straight for you. also the skeletons aren't controlled, they're automatically controlled and will attack whatever the closest target is (they also manaburn )
