That have been researching more powerful weaponry in the form of the guns you can research for the Normandy. Those puppies dusted a highly advanced Cruiser, so who knows what Dreadnought sized cannons of that type would do. Not to mention we have only seen one Dreadnought in the game and it was crewed by crappy Asari, where as a fleet of twenty something Cruisers killed a Reaper, what would happen in the "Final Battle" against the Reapers where you have dozens of Dreadnoughts? It would be a true Battle of the Titans.
You know, I actually think dreadnoughts would, as a whole, perform rather badly against Reapers and the human 'pioneering' with dedicated Fighter carriers would prove to be far more effective (and cheaper) against them. I say this because:
A) Their mention in ME2's codex as a form of foreshadowing

The Reapers were devastating against cruisers, while not confirmed of course, a fighter could prove harder to hit due to the firing lag the Reaper suffers with at least its main armament. We don't know if they have GARDIAN equivalents but it's safe to assume they might (if not at least their lightning conductive abilities). Fighters piloted by VI's at least would make them quite 'expendable.'
C) Thanix weapon systems can be mounted on Fighters.
I think the SR2 Normandy will prove to be quite effective against Reapers too.
