I think people are slightly missing the point here. Whilst on one hand it was supposed to be the least-optimal build for a playthrough (and btw, you can add more then one bonus powers with a save editor - hence Shredder Ammo and Fortification), it was still supposed to be crafted with some thought. Just making do without powers wasn't my intention. It was to
create the most-optimal build using the least-optimal weapons and powers (Heavy Shredder Ammmo, Area Inferno Grenade etc.), but I left it open so you could make that descision yourself.
Here's a clearer example of what I originally meant:
Hardened Adrenaline Rush
Shocktrooper
Heavy Concussive Shot
Area Inferno Grenade
Improved Shredder Ammo
LV1 Fortification
There's a really good series of youtube videos by thisisme8 called 'controlling the battlefield'. In the first few episodes, he makes frequent use of the Avenger and Concussive Shot, and not Adrenaline Rush. He's basically gimping himself in order to teach people how to play the game. I just wanted to gimp myself for fun (if such thing is even possible).
EDIT: That said, if you do manage to pull off a successful playthrough with an intentionally gimped Shepard, I'd love to see the video footage, if you have the ability to capture and post to youtube, for instance.
I would love to record myself playing, but I'm on the xbox, and I've got no capture card (though I'm seriously considering buying one). It was just a thought process to see if anyone could pull it off. Unfortunately, the poster above said it was boring to play

Back to the drawing board, eh?
