But Atkallen's post suggests something a little sneakier about the buff, which procs off of any trap snares or damage, or, more commonly, off of Black Arrow, another Survivalist talent. It used to proc off of Serpent Sting, from 3 to 10 percent of the time according to how many points you put into the talent, and when it was changed to the current form and lowered to 2, 4, and 6 percent, most Hunters worried that they wouldn't see it pop up as much. But here's the thing, and I can attest: it still shows up all the time.
The problem may lie in the tooltip -- for a while, it still said 3, 7 and 10% chance to proc, and that was scheduled to change in 3.1.2. It's fixed now though, and Atkallen speculates that maybe they were waiting to change the actual proc down too. But that was only the tooltip, and Atkallen is convinced that, anecdotally, LnL has something else going on. Finally, Voldenmist in the comments over there points out that LnL also had its own cooldown removed (which is why I can chain it occasionally), so that may have something to do with it as well -- maybe the procs coming closer together make it seem like more procs in general. Hunters, are you getting more LnL procs than you expect?
