Axe/SD Brute problems

So, by some twist of fate and fortune I've managed to survive 26 level as a Battle Axe/Shield Defense Brute. But that's slowly becoming and issue. I either run out of endurance due to the drain both power sets put out. Or I just have little survivability due to shields defensive abilities. Does anyone have some survival advice, as I do enjoy the set, however I feel less than mighty when I feel i constantly need some manner of buffer with me (FF,Sonic,Cold,Fire etc) Anyone versed in Shield Defense got any advice?

I'm about to come out with something I am a bit vague with because I looked into it in 2005.

Consider a complete build with no end slots in it. As your attack chaining away your toggles are running and the cost of the entire build and this could be the same for any AT is about 5 eps. Your toggles add up to about 1.5 eps, so your attacks are about 3.5 eps.

Now consider your attacks, if you have no damage slots in your attacks then you hit them once and do x damage, you then hit them again and do the same x damage, each costing y endurance, rather than hit them twice we double the damage we deal so that we do 2x damage for y endurance, this saves us y endurance.

Now going back to the second paragraph you can see that the attack chains take up the most eps and the third paragraph is about doing more damage per end through more damage slotting. If you only added more end slotting you increase the dam per end still but still you'll have to use the attack again, so thats two cast times and a longer fight duration.

All in all, economise your attacks before toggles, then see to the toggles.

Use brawl, use aggro from multiple targets to keep up fury then use aoes, aoes which you should now be thinking of putting damage slots in. Cone attacks on more than 2 targets will save endurance, aoe attacks on more than 4 targets will save endurance.

So now when I look at your build I'd be thinking too much end in toggles, not enough damage and end slots spread throughout all attacks.
