Take those two slots out of Sprint and put them into Health.
Swap one of the DEF or END enhancements in Energy Absorption for a 3rd Recharge.
Personally, I'd take taunt earlier if you plan to be a Tanker rather than a Scranker.
To make any more specific judgements it would be useful to know how you play. Team or Solo? Tanker or Scranker? Are you going primarily for Offence, Defence or a balance of the two?

I would change a few things:
CE: You can and should slot it with 1-2 Taunt durations.
EA: 3Rech2EndMod1DefBuff works fine for PvE. For PvP I use 3EndMod3Rech
Fire Ball: I think 1Acc3Dmg2Rech would work better.
*Edit*
I would take off Hurdle and Icicles and go for Stimulant + Aid-Self. It's not that you're gonna need it much, but it might be more useful than hurdle. Beside that, Icicles is quite end heavy and you already got enough AoE potential

a okies ty for the tips guys i will tell u how my build goes wen i ding lvl 50
well, my ice/fire/fire got her 50 last week.. and i can safely say that endurance is a ****, especially with fireball.
i have 3*dam 1*acc 1*end 1*rech in each AoE and have 3*dam 2*acc 1*end in the single targets. I also have less end redux in the shields than you, as they do relatively little end compared to the attacks and icicles/CE
icicles: 2*acc 2*dam 2*end
CE: 2*end 2*taunt
NRG absorbtion 2*end 3*rech 1*def.
i chose to slot char rather than fire blast. fire blast does about as much damage as scorch afaik, and char is incredibly useful for sappers, and with 2*rech 2*hold it can happily stack with iteslf for holding EBs. Personally i went cj, sj, hasten rather than hasten, ss, hurdle, cause cj gives a def boost.
lastly, as far as PvP is concerned. with its current build it can take down 'squishy' toons with relative ease. the only zone PvP i've done with it has been vs brutes, which have all ended in a no-score-draw. obviously, fire melee isn't great for PvP, but if you fancy giving it a go; drop icicles, get aid self, drop combustion, get foc acc and conserve power for epics, take fire sword... stick an extra end mod in NRG absorb... and take lots of red insps with you. 
hiya guys i am enjoying my ice/fire tanker its the first one i have made so here is my build plz comment as i need the help ty.
