Updated: The below post is now irrelevant as Celestalon tweeted there’s going to be another change to Lock and Load. Every time one of Black Arrow’s ticks multistrikes, it adds a stack of Lock and Load.
One of the changes coming in Warlords of Draenor for survival hunters is that every Black Arrow will guarantee at least one Lock and Load proc. Traps can no longer proc Lock and Load, which is why LnL itself has been removed and it’s now just a built-in component of Black Arrow.
Some hunters were wondering exactly how this guaranteed proc was going to work. Did it just mean that the final tick was always guaranteed to be a proc, or what? Turns out, that the guaranteed proc is randomly placed on one of the ticks, and it does this by determining how many procs you get on cast and then randomly placing them among the ticks.
@WayethGaidin Proc count starts at 1, then it has successive 20% chances to add 1, until it fails a roll.
