this is a joke right?
Nope.
But thanks for the..eherm comment!
One of the problems you'll have with hover/flight is the inability to use ice patch unless you switch it off, which is a pain. I'd reccommend CJ/SJ/Acrobatics instead.
I'd also say, especially for pve, you get ball lightning and short circuit. combine this with ice patch, chilling embrace and you have high survivability, and good aoe damage output.
Get both frozen fists and ice sword if possible too.
Aid self is certainly an option and a handy one.
I didn't like shiver, found the options in the elec primary options were better and as a blaster you need the damage output.
Oh, and avoid frozen aura like the plague. 
Not had much experience with /Ice but going from what you said I would suggest something like this bud:

If you wanted Acrobatics take out charged bolt, hover and fly.
As far as PvP goes take aim and build up and hope your rage attacks, holds, and shiver are enough but a pure pvp spec Ele/Ice would be awful in PvE

Not really, although you can get a very nice mix with this as demonstrated below...a masterminds nightmare

Is a perfectly adequate pvp/pve build, might be over slotted though..no planner so a cut and paste job.
y the hell wud you wana get voltaic sentinal, its beyond awful!
wouldnt bother with aid self either, just carry a few greens around. I would also get ice patch and chilling embrace, both are great for crowd control which is important for a blaster i found on my lvl 50 elec/ice/ice.
If you have any other questions then just send me an ingame tell @Electrode.

[/ QUOTE ]FYI, while chilblain is slightly higher END cost, it's much better DPA and somewhat better DPS than C-bolts. (Although the range is a bit shorter)
That's pretty much irrelevant however, given there are very few situations where you'd be repeatedly spamming the poorest attack in your attack chain. Add that to the fact that endurance is going to be a bit of an issue with this combination and I'd go for the lower endurance cost attack, and keep the immobilise to do exactly that.
If you wanted to make use of the immobilise in PvP for it's minus fly capability, it may be worth sticking a couple of accuracy enhancements and possibly a range enhancer in there, but for a build primarily geared towards PvE, I simply wouldn't bother with anything more than the default slot - the only time it's of real use is in AV fights.
To the initial question:
Elec/Ice overall you're not talking about a high damage build, also a bit of a contradiction. The main benefit of /Ice is that it does make it possible for you to really keep enemies at range. Ice Patch and Shiver are excellent tools for this, however in order to get the most out of your limited damage capability you're really going to have to go in to mele.
For a PvE build I'd use Ball Lightning and Short Circuit for AOEs. Short Circuit on it's own for endurance drain isn't worth the trouble (definitely not worth slotting for it), but the damage is OK for an AOE, so three slotted for damage you can really increase your overall damage output especially in team situations.
Charged Bolts, Lightning Bolt, Ice Sword and probably Frozen Fists I'd go with for single target damage, slotting combination of accuracy, damage, recharge and endurance reducers as required.
Voltaic Sentinal I avoid like the plague. The damage is not that great, it's damage over time not burst damage, it's not buffable, it's not controllable, it costs a lot of endurance.
Shiver is absolutely fantastic as slows go, and slows are damn useful anyway. Slotted with two accuracy and two slows (plus probably one endurance reducer, you'd need it I think on most builds) can be extremely useful in cutting down on the damage taken.
Ice Patch is lovely, particularly for soloing, works fine straight out the box, one recharge and you're sorted.
Tesla Cage and Freezing Touch will make handing bosses quite easy although it wont be as quick as on some higher damage builds, slotted both for accuracy and holds, plus probably and endurance reducer in Freezing Touch (the cost isn't as heavy as, for example, Shocking Grasp, but it's still quite a chunk for a set that gets no endurance recovery power).
Pool power wise I agree that Hasten would be very useful, you're not exactly wading in great high damage attacks so having the best ones available as often as possible will certainly be advisable.
Flight does not mesh with /Ice at all. You need to be on the ground to use Ice Patch, which then means you're losing all your knockback protection when you want to use it. In addition to which as overall the build is almost going to have to include a fair amount of time in mele to get a reasonable level of damage, I'd want leaping for it's hold/knockback protection.
Would that work for casual PvP? As well as any casual PvP build works. I tend to find that zone PvP with casual builds in teams of two or three works very well, probably not in the arena.
Elec/Ice overall is going to be best for team PvP basically because it's not an awesome combination for PvP, but could be tweaked to cause people some real problems. Combine slows and -fly with a character that does reasonably good damage output and you start to cause a lot of character types issues - if you try and make a conventional Blapper type PvP build it wont work, so you'd need to do something a little more original.
Have fun.
Would appreciate any ideas on a mainly PvE build (occasionally PvP).
I want to get flight back (keep fitness/speed [for hasten]), but I'm not sure whether to get medicine or leadership. FoN will be my epic set.
Any help would be appreciated, Thanks
