You're still very obviously a bot. For my product, I reworked all the routes, added offmeshes and made the bot follow objects as well as possible.
Even then, you still end up getting reported. Maybe not on massive Russian WotLK servers where nobody cares anyway.
I have probably 3-4k hours of BG botting under my hood just with WRobot between Vanilla, TBC and Wrath. Trust me, when I say that just fixing the pathing itself won't be enough to not get caught.
