I'd drop lightning clap and take confuse, this would also free a few slots, that could be put in mass confuse (ConfDur), Steamy mist (DamRes), and Hasten (Rech).
I can only really help on Storm...
Gale: one slot for accuracy
Freezing Rain: 3 Rch
2/3 end rdx in hurricane, if you run it as a constant toggle
Steamy mist: 2/3 End Rdx & 3 Dmg Res
Thunderclap= no
Lightning storm: 3 dmg + maybe one rch
Hasten: A lot earlier, as it's v useful for storm, and it means you can 3 slot it.

Idea behind build; a group based controller offering as much damage mitigation to the team therefore getting as many control options as possible back up as quickly as possible, once near end game my start PVP however would probably respec along the lines of the choices listed below.
Choices I made;
No mesmerise Mesmerise is a single target sleep so will probably become less useful in the later game, while I am taking this to 1st respec, plan to respec out of it. however build is not very damaging so should it be kept for that alone option and lose mass hypnosis. Can be useful to stop runners approaching you or other squishies (their fault if they hit a sleeping mob)
No confusion Again how much use will it get late game? Long animation time, single mob target. Again though is good for taking away unwanted attention from yourself or others and is stackable on bosses also has good duration. Possibly lose thunderclap.
Took levitate over above 2 because the damage is good, recharge is good also allows you to dominate-levitate-dominate bosses while receiving little or no damage.
No O2 Boost One of the lowest heals I believe in the game, let others do that my time better spent doing other things.
No Tornado Never tried or seen this power however I do not like the sound of something that sounds somewhat unpredictable.
Epics, I chose Ice to fit in concept wise with storm, I have put hibernate in there however would the blast be better for damage? As Im unsure how useful hibernate is thought I could use it as health and end regenerator. My other thought was to take the 2 blasts from fire then put assault and tactics in.
