I totally understand where your coming from.
But.
As an Anni Mara, if that is how your spec'd, our greatest dps multiplier is chain killing. As a lone example take your form proc, once you have 5 stacks our dps really comes alive. Why waste your hard earned dps boost, it lasts (i forget) 5-7 sec after combat, only to lose it between fights resting for health. It is a class defining ability.
Now, that being said. It's your toon, you pay for it and you have to play it. Do what makes you comfortable out there.
Like other posters have stated, any companion you use should be geared as well as you can afford to get them. If you plan on using a dps or tank companion you really should be biochem spec, imo. Also work on mastering your defensive ability's. I have no play style tips, once I got Quinn I parked all other companions.
Have fun and good luck.
