I usually refresh NT on Sha and his adds before I fly away behind them. I never thought about using Arc Exp on the platform add. I use it on every other fight so my 6 stack doesn't fall off. Good tip.
I tried cauterize, which is perfectly safe to use on annhiliation, but you will need heals of course. Invis will leave you above the threshold for the stun I think, since the damage is only 500k (in 10 man). We left it to our 2 warlocks and monk dps as they seemed to have an easier time not losing dps and doing the soak.
on a side note, for heroic blade lord if you top down view during the tornado, you can blink out and then ease back in close enough that improved AE will hit him to keep your stacks. It isn't necessarily the safest thing to do, but it is safer than trying to turn and quick cast a missles proc.
Also, I thought I noticed that the sonic pools on empress reset my stacks with AE too... though I could have imagined it.
Finally, I also noticed that if you are chain casting or channeling on Sha when you get cackled, you don't fly off right away. The last 2 kills I've been teleported to him by nonstop casting then hitting invocation. This puts me at the outside platform with full stacks and a full invoker's buff. Also, I save a missles for coming out from behind the pillar from death blossom or if we are really pressed for dps, I iceblock near him so I can AE and maintain stacks. This usually puts me at the platform. I dunno if it is just luck or if it is something I'm able to manipulate.

Yeah the only time you should lose stacks on Heroic Elegon is if you're soaking (let's face it, Mages are virtually the best class for that what with GI and TS) or if no adds spawn on your side at the end of the phase where you're DPSing pillars.
Two Arcane Missiles back to back will destroy every spark guaranteed, and there's enough time between spawns to easily bank two of them by using AB and Scorch on Elegon.
I'm honestly not sure there's a better class for killing sparks, though I can't claim to have raided with many other since Cataclysm :P
There is nothing better than Arcane Mage for killing sparks. On 25M HC I can nearly solo the 5th wave.
I still only usually lose it on soaking if I'm not fully healed up before it explodes (so I get stunned) but yeah, it's easily possible to keep it then too.
