Full Elemental Wand Witch

Hi there,
so I've been playing for a bit now. Unfortunately, I don't have a lot of time, so I focused completely on the witch.
I started out as a typical cold-crit-witch which worked perfectly fine, but I really wanted to try using wands.
After reading the forum carefully, I obviously went with CI and weapon elemental damage and took the shortest path to get there.
Without further ado, here's my current build (I started this at lvl 28, so I can't say anything about the early game!):
EleWandWitch

I'm maily using this spell combo:

With auras (hatred not included):

I have two more hotkeys with Elemental Weakness and Discharge, which I barely every use!

In the long run, my calculations indicate that Elemental hit will probably do more damage (I find it really hard to calculate!), so I level it up as well, but I cant use it efficiently because I dont have the proper socket-color combinations (and it's not as high in lvl yet).

The build is pretty powerful and mostly fun, but there are some issues, I'd like to mention/discuss:
1. I simply can't find any multiple projectile gem, which pisses me off (same for bloodrage, btw). At this point, that is by far the most annoying dawback and the only reason, I kept playing is that I 1-shot nearly everything with rather high attack speed. Even rares usually fall before they reach me (1-2 crits help). Still, I really need to trade one or level an archer to lvl 20 (would that work? do I get one as quest reward?).
2. Mana problems. I read a lot of comments saying IC is enough to solve health and mana issues completely. Well, in general I'd agree ... for lvl 25-40. But as the gready player I am, I insist on running around with Anger, Wrath, Hatred and Discipline. That leaves around 150 mana for my 45 mana power siphon. Still, I don't really have a problem with it. I just pop a mana potion whenever I start shooting, essentially giving me max mana regen at all time. And if there's an auto attack in between my skill shots, that's fine by me.
3. Hit chance is a problem (80% atm). This is annoying, but I try to compensate this mainly with dex-gear, since I'm planning to use elemental hit with multiple projectiles later on.
4. Well, I'm kind of a glass cannon. It's starting to get annoying, but I can still take 2-3 hits from dangerous enemies, so I'm not really concered (I also carry 2 granite flask). For the next level ups I'll invest in ES and cooldown reduction and I should be fine. Also, my gear sucks! Big time!

Actually, I'm posting this because I'm probably not going to play this char much more. In case of a passive reset, she'll be history because there's so much other stuff I wanna test and I don't have time to level up more than 1 char.

As closure, I'd like to show you my max elemental wand witch build that I will probably never reach:
MaxEleWand
It's 73 points with very little defense. I think for a more realistic build, I'd cut either some crit points or the +60% weapon elemental damage for many extra points. But I'll let someone else try around there.

Okay, that's my story of playing PoE for about a month. Any comments or questions?

I daresay that once you hit merciless, you are going to have a problem with the mob size, even with multiple projectiles. Because of how squishy you are, you are probably going to need a decoy totem or some zombies to keep mobs occupied.

And get some more ES man, I am shuddering thinking as to how little ES you have. Put quality on your items as well.

Ha, yeah, I know.
Every new passive will go into ES. And I don't want to waste my scrap on low- or mid-lvl items; at least not yet.
As I said, I'm not really playing this character anymore and I'd need to do some trading before it becomes viable for the next difficulty.

Edit: for completion, this is my suggestion for the end-game spec:
