hmm.
first of all - you can't have 2 archons or archites in a single army.
then i would suggest you to load all of the 10 warrior squads into raiders, dropping 1 splinter cannon and 1 blaster from each. and finaly - i would suggest replacing the splinter canons with dark lances in the 20 men squads.
oh, and you will get slaughtered in CC. even with 80 warriors - specialised CC armies like nids and orks will kill you, as well as super-shooty armies like tau and IG.
get some CC squads in.
