I suspect this is your toon:

If so I would first of all suggest using either AMR's experimental reforging or Zypherus (
https://dl.dropboxusercontent.com/u/...rus-Latest.zip) for reforging. that should maximize your Rune. Since you just got the heroic Staff, It's not advisable to switch to 2 1-handers until you get 2 Heroic 1-hand weapons (doesn't matter which ones).
Jin'rok - Diffuse Magic is a must to negate the Ionization. Hold off on popping everything until the first puddle
Horridon - You can do 1 of 2 ways, you can cheese the meters by keeping a SEF on the boss when dealing with adds (but you are not helping the raid by doing so) or keep SEF on the most important adds and you on the small adds. Also Ring of Peace is REALLY good for Door 2 and 4 to interupt the adds.
Council - Use SEF on the healer, and the Frost King while attacking the sand guy. Once the sand guy is dead take off a SEF from either the healer or Frost King and put the SEF on the rolling guy; and switch to the the add without SEF. Diffuse Magic is good for soaking a few more stacks of the debuff on heroic than normal (or if a moron in raid decides to pass it back to you after already sent it off already)
Tortos - based on your logs, it appears your using the kite method. So all I can say is to get Dampen Harm and switch between Dampen harm and ToK for each and every stomp.
Megara - Again you can cheese the meters by popping SEF on the head your not attacking, but again not helping. Diffuse Magic is good for the acid bombs as well as every other Rampage (ToK on odd-number Rampage). Heroic I would suggest picking up Rushign Jade Wind for the adds that appear.
Ji'kun - I found Momentum to be extremely useful for the push back (2 rolls and I'm not moving). Again RJW is useful for the small adds
Durumu - One trick I've found is using SEF on the Red add (generally in the red beam myself) while continuing dpsing the boss.
Primordius - Not much to say other than DO NOT USE DIFFUSE MAGIC unless you are not tranformed. You will loose all of your buffs/debuffs.
Dark Animus - ToK and Diffuse magic are very good for Interupting Jolt
Iron Qon - Again ToK and Diffuse Magic are very good for this fight, especially when the red dog is up (his fire attacks hurt)
Twin Consorts - depending on what your strat will be, your raid might require you to kite Sun during Night phase to purposely pop the shadow adds (FSK and Celerity are nice for that strat). Otherwise Diffuse Magic and ToK for the Fire AOE during the Sun phase is a must.
Lei Shen - I use Momentum (if my FSK is on cd for Helm of Command), Leg Sweep for the adds in Phase 2 and 3, and Diffuse Magic for the Static Shock.
