Thank you for the replies and suggestions, and I'll fill out the template for new members right away!
Those were some definite good suggestions, especially Nic's suggestion to deepstrike plasma crisis suits.
The game we played was 1200 points, and being a newer Tau player, I haven't assembled a particularly large or diverse roster as of yet, but it's still a work in progress.
My list is mainly composed of Firewarriors, Kroot, and Pathfinders, with plenty of drones, three crisis suits, three stealth suits, a piranha (with seeker missile of course), and led by an Ethereal.
Essentially it's a footslogging army at this point, which for obvious reasons struggles in a lot of aspects.
His list consisted of practically all infantry as well, save for a single weapons platform, a Falcon, and a Farseer on a jetbike riding around being a royal pain.
He fielded about nine Dark Reapers, and because we were playing Dawn of War deployment, they could basically sit back and form a static firing line that chewed my squishy infantry to pieces.
Unfortunately, these guys were also guarded by a 6 man squad of Warp Spiders which also proved to be effective, since they could teleport into my flanks and wreak havoc.
Rather than move forward toward his army line and utilizing the 4+ cover halfway between us, I attempted to flank from two different sides to converge on the center which ended up not working very well. I feel I should have moved forward and taken the casualties, the idea being that he wouldn't have been able to kill all of us, and I may have even been able to put out a rain of plasma fire with Storm of Fire and rapid fire range.
All in all, it was just a fun casual game and I'm learning a lot about playing the Tau and building effective lists against the Eldar trickery. I think the next order of business is to add some more Crisis suits, and possibly even more Piranhas, as those fast-skimmers were really the most effective way for me to rush in and unleash some burst cannon volleys into him at close range. What a glorious way to drop those Howling Banshees and Guardians.
