I'd suggest skipping Titan Sweep, as the set already has tons of AoE without it (though I wouldn't skip it leveling up). Otherwise, I would consider, in this order: CB>AoD>BM
Really though, the only power that screams to be skipped is taunt, though I generally play scrankers if I play tankers at all.
TW/Elec Optimization
If you must skip one attack in TW, I'd go with Titan Sweep. If you must skip a second, Crushing Blow.
I would rather not skip either of those while leveling, though.
Like a lot of people, I'm giving TW a try. But in the build that I have planned, I have to drop two powers from Titan Weapons. In your opinion, what's considered skippable? I will most likely drop Taunt and just make a second build with Taunt for when it's needed (AVs, etc.). But all of the other powers look pretty tempting, so I'm not sure what else to get rid of.
