Couple things:
Wild Hunt - atm its broken on PTR, doesn't do anything. But I'd imagine its 40% more than the current amount, not the current amount plus an additional 40%. As you can see by the default settings on the latest version it's giving 800 dps per pet talent point.
EDIT: seems wild hunt not working for me on PTR was a display bug. ignore this point I guess, nerf inc tho!
LnL - Late here, going to have trouble explaining this, but by my calculations the most accurate figure you can give shots replaced for LnL is 1.5 (no interleaving). Currently the spreadsheet only offers 1/2/3. I'll try do a diagram...
First row is without LnL procs, second is with.
X = explosive shot
- = filler
X---X---X---X---X---X---X---X---X---X---X
XXX---X---X---X---X---X---X---X---X---XXX
or more simply (2consecutive procs)
So your gaining 3 explosive shots from 2 procs. So 1.5 shots replaced every proc. Of course this is neglecting the fact the player will likely wait another 0.1 seconds before firing to ensure the final tick goes off... but thats probably beyond whats necessary.
