Im really liking the triarch stalkers.
armor 13 walker with a heavy 2 multimelta that can be fired as a flamer.
24" range, but if your using solar pulse, you can walk him up before your opponent gets a clear shot at it.
Any HITS scored let the rest of your army gain twin-linked if they fire at the taget that was marked? yes please
at 150 points, I'm considering running at least 2 of them.
