According to the some developer posts, Soul Reaping will be changed by only allowing energy gain once every 5 seconds.
This was to stop abuse from N/Rts spirit spamming and having plenty of energy, apparently.
To be honest, I think they should just stop energy gain from spirits altogether: if you get energy from a spirit, then something else dies (giving you the full Soul Reaping benefit), you still don't get that. Also, Animate Bone Fiend is still 25, with a recast of 5 seconds. Including the cast time, it won't even out as well as it did before (this is strictly in PvE, though), where you'd pretty much be able to cast it as soon as it's up.
Personally, I'd prefer the energy gain rate to be 2-3 seconds, and then exclude any spirit's deaths for energy gain (since it looks like this route is the way they're going to change SR).
What do you think?
