Little blue post referring to refreshing DoTs:
Dots and hots adjust on the fly now when they’re refreshed. There is less reason to try and get everything lined up perfectly for big numbers before you cast the spell. You’ll be able to game it a little bit for the initial spell duration, but it won’t refresh infinitely with the big numbers.
We have to rebalance the entire game anyway given the magnitude of the Cataclysm changes, so don’t worry about being penalized for any old mechanics that may no longer be relevant
I read this as basically saying that our little trick of using Chimera Shot to refresh %damage or crit increases is going away. No biggie, but good to know. We’ll do some testing to be sure once we get up to level 85 and things are more set in stone in the beta.
Actually, the “when they’re refreshed” seems to indicate its going to all hots and dots. Only change is that it wont last the entire fight, but only from the first refresh after a buff is applied untill the first refresh after the buff is gone.
So itll depend on the strength of serpent, either very interesting mechanic (timing chimera shots slightly) if serpent deals good damage – or plain ignorable.
