Lol @ quieter.
On the damage calcs - I do think you need to take into account the environments a bit:
In PvP, most MPs whose builds rely on weapon damage will want to go with Ranged. There are many issues with going melee in PvP.
In PvP, MPs who want to focus more on nuke damage and casting, will tend to go with 1HB for the mods and defence more than for the damage (though if they're forced into melee, that will still be an good option).
In team PvM, I could see the 2HB coming into its own more - because of pushing the agg-def bar up. No need for being full-def in team PvM and in your calcs, being full def on the slow weapon is always going to be a killer.
In solo PvM, you can see 1HB coming into its own more as a damage dealer. Many 1HB solo MPs engage much more in melee alongside their pets - going full-def and with the shields offering them the defences to do so.... and who knows? Maybe the parry shield will be the shield of choice?
These also happen to be pretty much how the various weapon types are mostly used at the moment. PvP MPs want range and use ranged weapons of buffing shield set-ups, 2HB tends to get used for team PvM, hard solo specialists tend to go 1HB/Shields - maybe switching to dual wield when teaming.
