Build Help - Dark/Storm/Fire/Sorcery Controller

[Spellbook-Everlasting]

I really love the concept of Sorcery and when I found a name that actually got me excited to try and use it, I had to give it a shot.  I got a build before, but it just wasn't what I was looking for.  So, since Storm is such an End hog, I did concentrate more on endurance recovery overall.  This is more of a team build, not solo build, so the defenses and resistances are middling, but I figured this could be enjoyable in a team setting.  

 

Thoughts?

• You're over the cap on the 4.0% and 2.5% end recovery bonuses. You can't have more than 5 of each. Rather than focusing on end recovery, slot end reduction in the powers that use the most endurance (Tornado, Lightning Storm). 
• Swap the positions of the Numina +regen/recovery and the Preventative Medicine +absorb. Numina needs to be slotted in an active power, PM does not.
• Energy Font is crappy to begin with, but its chances of firing in Dark Grasp are really low (21% with the recharge you have slotted).
• The chance for procs to fire in Living Shadows is really low, and slotting for recharge makes it worse. You're at about 15% for the 3.5 PPM proc and 20% for the 5 PPM. Slotting for tohit debuff also doesn't yield great results since the base value is so low. I would drop slots from this power to deploy elsewhere.
• Fearsome Stare should be slotted for tohit debuff, not fear. Slot Siphon Insight or Cloud Senses. 
• Steamy Mist should be 6 slotted. Drop the Steadfast res/end and -kb pieces and slot Unbreakable Guard or Gladiator's Armor res and res/end. Add Shield Wall def and def/end.
• Enflame needs more accuracy and end reduction.
• Add another slot to Heart of Darkness for the recharge bonus.
• Haunt is overslotted for damage. 5-slot with Expedient Reinforcement plus the Call to Arms def bonus.
• In Shadow Field, swap the %dmg proc for hold duration.
• 6-slot Umbra Beast with Expedient Reinforcement, not Call to Arms. Call to Arms caps at lvl 30.
• Slot Tornado w/ Expedient Reinforcement (skip the acc/rech and resist bonus), not Call to Arms.
• Lightning Storm should be slotted with a ranged damage set, not an endmod set. It needs more than 3 slots and it needs end reduction.
• Freezing Rain should be slotted with 2 recharge IOs. You should take it as soon as it becomes available at lvl 16.
• Drop the endmod/acc from Stamina and add the Miracle +end to Health.
• Drop something for Rune of Protection. If you're already 3 deep in Sorcery, it's too good to skip.
• I would consider dropping the Fighting pool entirely and picking up Maneuvers or Combat Jumping to carry the pieces currently in Weave. The pieces in Tough can move to Fire Shield. I wouldn't bother with the psi resist pieces.
