Exactly, the build I tossed out there is intended as end-game.
What you're looking for in the interim isn't so much a BUILD as a STRATEGY.
(I had a friend who didn't understand this and tried to level an end-game build up from L1.
All I can say is:
Resist Armors: 2 Resists, 1 EndRedux (The Resist Physical Damage/Resist Elements/Resist Energy are no-Endurance auto powers, so just go 2x Resist
Defense Armors: 2 Defense, 1 EndRedux
Attacks: 2 Acc, 2 Damage, 1 Recharge, 1 End Redux
Work on your Accoldaes. Atlas Medallion, Freedom Phalanx Reserve/Born In Battle/Marshall. The ones that bump your End.
Then work after the +Health ones.
Keep an eye out for the +Defense/+Resist uniques for cheap.
This'll actually leave you with a build with lots of slack space in it. ESPECIALLY at higher levels.
Use the slack space for Health and Recharge
Stick with SOs until your 30's.
They may SEEM like a huge investment.
But stick with taking the SOs are the highest available level, then just keep it there until you're about to out-level it, THEN UPGRADE!
In the long run, it'll be less expensive.
Once you are able to load L35 IOs, go ahead. And as you level up, just fill new slots with new, highest available level IOs.
Once you start pushing into the 45-50 range, start prepping for the final respec.
