I run top tree pretty regularly and we need to stop being crybabies. Yes I've seen people skip through what I felt was a good tether shot (reasonable amount of leading) and yes it's annoying. However the reason we run it in PvP is for the invis on dodge + the ability to practically spam it every 10 seconds + combine it with gamblers dodge to have a nearly guaranteed escape in any situation. Plus the smoke is super effective and has proximity detonation. It's absolutely top tier even with the underwhelming super. Buffing the super to activate immediately or tether more strongly would make it the dominant meta for hunters. As is it now, it's great and the super keeps it somewhat balanced. If you want an amazing super, use middle tree and give up constant invis - it's a fair tradeoff.
