Online and testing aswell
So far I found out u probably havent read about the new ability called Pandemic
"In Warlords of Draenor all damage over time effects now have a mechanic called Pandemic. Pandemic allows you to carry over up to 30% of the base duration of the new effect from the old one's duration. For example, if you apply a Rake to a target that has a Rake with 4 seconds remaining already on it, the duration of the new Rake will be 15 (base duration) + 4 (remaining duration, <= 30% of 15) = 19 seconds. It is important to take advantage of this mechanic for optimal DPS, the main takeaway being that all DoTs can be refreshed as soon as they have <= 30% of the base duration remaining. The sooner you reapply a DoT, the less chance you stand of letting it fall off, which means higher uptime and more damage. This mechanic allows for significantly easier maintenance of our bleeds and Savage Roar compared to 5.4."

This brings up alot of potential for timing when u re-apply bleeds, to snapshot from Tigers Fury and Bloodtalons at lvl 100. Also will be alot easier to keep savage roar and bleeds uptime higher
Hope this helps, will post if I find anything else.
