So I'm a SimCraft noob when it comes to APL's and such, but I've been playing around with the latest compiled download at http://downloads.simulationcraft.org/ just out of curiousity, and I wanted to suggest one improvement to the Affliction SB:H APL. Before the two lines doing the Soulburn + Haunt combo, I added this one:
Code:
actions+=/haunt,if=shard_react&talent.soulburn_haunt.enabled&!in_flight_to_target&!buff.soulburn.up&buff.haunting_spirits.remains>4&soul_shard=4
Which basically states (I think) that if you manage to hit 4 shards with the Haunting Spirits buff still up on you, you just fire off a normal haunt avoid wasting shards or buff time. This resulted in a gain that puts it rivaling the DPS of picking Cata on Patchwerk fights. Haunting Spirits uptime drops a bit, but Haunt debuff uptime rises.
Now this line was just hurriedly added so I have no idea if it's perfectly optimal or not, and I also know tuning is still happening on Beta so there's no point spending toooo much time refining an APL, but I figured I'd mention it anyway as this has naturally been the way I've been playing my Lock with the SB:H talent anyway on beta (i.e. cast normal haunts if you're in danger of wasting shards or buff uptime).
