People like the two of you are the reason we have those "Cruisers are useless" threads. You HAVE TO max out your dps, both to contribute towards group-dps AND to be able to generate enough threat to actually tank.
Gimp your damage, and all you do is be insignificant.
Umm... how should I begin to address this one?
1. The two builds I posted contain 6 Tactical powers for the Tac Ody and 5 for the Sci Ody. You can shuffle the powers around a bit, but aren't going to find a workable Ody setup that has more DPS potential than that combination of BOFFs.
2. The only "utility" build I posted was an alternative combo for the Tac Ody, this was used to very good effect in 'keepaway' missions like CSE - it's capable of handling two Kang attack waves simultaneously, and both TBR and GW1 are actually pretty good for pulling hate from multiple targets. This is not the only workable alternative build I've used for an Odyssey.
3. That Weapons "Buffer power drain beyond 125" bit you mentioned as the basis for your argument?
(i) It only applies for beams.
(ii) The increase in DPS isn't nearly as noticable as it first appears, in fact, the extra DPS for every point over 125 drops off very sharply (and incidentally, the Tac Ody can hit 130 before you even start adding Weapons Power Consoles).
Threat Control acts as a damage impact multiplier. A Cruiser using a reasonable amount of DPS will pull aggro off a well-kitted-out Escort, assuming that Escort does not also have points invested into threat control.
You'll notice that there's quite a lot of debate in many of those threads linked between myself and ussultimatum: we're not just agreeing with each other for the sake of it here.
You do not NEED maximum possible defence, just as you do not NEED maximum possible Damage output. It's always helpful to try to push your DPS up once you've got the rest of your build sorted, but it shouldn't be the only thing you focus on.
Reasonable DPS and heavy investment into Threat Control is one half of making a decent Tank. Sufficient survivability and mobility are the other half. It's possible to cover both those halfs sufficiently and still have powerslots left over, especially on an Odyssey.
That's not to say there aren't some piss-poor builds flying around out there (and I've met most of them in PUG STFs - Cruisers, Carriers and Escorts - the Ody is no exception!) but don't judge what's POSSIBLE by what you've seen someone manage to do (or more likely, by what you've seen them "not manage to do")
