Couple things --
You have Super Jump at level 28. You could take Inertial Reduction at 28 to get the same effect, without needing Combat Jumping. Though it seems you were interested in Acrobatics, so maybe that's why.
I would swap out Leaping pool for Aim, Inertial Reduction, and Increased Density.
You won't be able to get a lot of defense AND perma recharge. In fact, with this sort of build I'd probably forgo a defense build. Ice/ is pretty survivable as it is, and the returns on an expensive defense build wouldn't be there. That's my guess anyhow. You could consider going for soft capped range defense (that's 45%), but if you're jumping in to get most of your Fulcrum Shift then that won't be a huge help. You can always FS from outside the group and just let the melee characters soak it up. You and your nearby ranged friends would just get a smaller damage buff.
I see from Scorpion Shield that S/L defense might be more your cup of tea. Consider getting the Arena and PvP day jobs for the Combat Shield temp power. Also, Kinetic Dampener is a craftable temp power. They are both somewhat expensive (on endurance) temp powers for S/L defense. They can really come in handy in dicey situations and stack well with Scorpion Shield.
Honestly, as far as making an effective IO build for cheap down the road, I would start low bidding on 5 full Thunderstrike sets. They won't need to be top level. You can skimp on the Damage and Damage/Acc pieces in particular, as the set will add global accuracy and it will max out damage even at the lowest possible level. Add a full set of Lockdown for Web Cocoon and you'll have something like 25% ranged defense.
Low bid on 2 Positron's Blasts as well. More global accuracy, some recharge.
S/L defense builds aren't cheap.
@Gilia1
I play heroes on Champion.
I play villains on Virtue.
Let me start off saying that I am new to Corruptors. I have mostly played Blue side and w/ GR out, I wanted to try the Red ATs. I am looking for a well rounded build that can solo or work well in PUGs. I plan on soloing this toon thru Preatoria, since I like the current misson arcs. Then once I am out in the older areas, I think I will try to PUG as much as possible, but that does not always work at the times I can play.
Here is the build that I plan to use to level. I have everything sloted for SO as a marker for what enh I would choose. I usually start swapping out the SO for base IOs at 35. I may even Frankenslot if I get decent recipes.
Also, if someone can post a towards the cheaper side lvl 50 IO respec build That would be appreciated. I think I would be looking for +def, +rech (want hasten almost perma if possible cheap), +acc or to hit, and +end rech. Not good with IO sets, so not sure how viable it would be to get them all.
Now here is the leveling build I have so far.
