Speaking from personal experience, I use the ares with the vulcan. I am amazed bye the endless possibilities streaming from this one set up alone. Acting as a middle-fielding support tank, chipping away large chunks of health very opponents to assist team kills or kill 1hp tanks scores alot of points and can save you and your team from difficult scenarios and is my favored playing style. Using this the with the fire immunity and fire rounds augments is a very formidable set up not only granting immunity to firebird and overheat, but quickly set enemies on fire. This can be very suitable for shoot n hiding situations. Other long range support weapons- most notably shaft and gauss- are good combinations too. Overall I think guass is a really great vehicle and as many ways to counter its disadvantages. The only concept I don't appreciate is the slow speed the overdrive projectile has.
