Well Jinada is not working and if you want to copy the real Dota 2 track, use Faerie Fire ability because that is what Track is based on. However I suggest to use a different mechanism for track where the Track Indicator (Footprint overhead) is only visible to player or allies of player that cast the Track. The number of abilities is also lacking. How about adding a long range abilities such as "Boomerang Blades" where the target is location and the effects are like Timber's Chakram but automatically comes back unlike Chakram where you have to click again to retract chakram. The number of items is also lacking. Make items that can be related to BH. Example, create an item that when activated, it will reflect the Track effects or something. Instead of you being tracked, the one who tracked you will be the tracked.
EDIT: You also might want to add runes. Another ability suggestion (or item ability) is called Hunter's Eye something that grants 100% evasion for a few sec. Another ability suggestion if you like is an ability that camouflage you as a tree. BH turns you into a tree but giving any orders (move, shuriken, track) will reveal yourself and transform you back to BH.
