There's a fine array of bows. Though I will admit that other weapon types (such as daggers, staves, etc) are lacking.
In terms of 'swords' I'm not sure if you're including two-handed weapons or just one-handed. As I think the two-handed weapons (or at least good ones) are hard to find. Or are only found through confusing side-missions (coughcough Yusaris coughcough).
I don't play tanks all that much, but I did do a One-Handed/Shield PT and it was remarkably easy to find good weapons. (Ended up with: Starfang + Fade Wall.)
The DLCs are the best way to get gear that isn't focused solely on the Warrior Class. Awakening and Soldier's Peak (provided you're high level when you start the DLC) probably provide some of the better equipment.
Also I suppose it almost makes sense that the more powerful weapons would be found in odd ways. Ways that the player wouldn't expect, and might just ignore. Not knowing how easy it is to obtain them, and trying to look for more convoluted ways.
All-in-all, it does kind of suck that the Warriors seem to get the better gear. Though with so many people loving to play tanks I can see why BioWare focused more of their effort on tank-related equipment.
