Lol, I admit, Artanis’ Dragoons might possibly be a little too good. They’re very long range, deal good damage, can attack air and ground, move reasonably fast, are fairly tanky, and are cheap and replaceable. Combine that with Guardian Shell and it’s pretty easy to see why people (myself included) see little reason to build anything but Dragoons on most missions. But yeah, Artanis has other good units. I’m personally also a big fan of the Reavers, since they cover one of the Dragoon’s main weaknesses, that being swarms of fast units like Zerglings.
