Set it up where you can have 2x5 or 1x10 and 1 Heavy weapon (DL), Its really easy with the Start Collections b.c you also have the Raider you can use the guys that are Handing off as a Special weapon and a 2nd Sybarite. This will get you 2 more bodies to play around with. You can then have your DL kabal and another Sybarite.
The Guys that hand off honestly just get in the way, but if you really wanted to keep them on thats fine too.
DL's on Kabals are fine in Raiders, if you are putting them in Venoms i wouldnt use a DL on them.
As for the Archon, i have 6? of them all kitted differently, sometimes i like Agoniser, sometimes i like the Huskblade. If you fighting lots T3 the Husk is better, otherwise the Agoniser is better.
As for the Blast Pistol? I like them, but i also put them on all my Sybarites and Dracons.
Dont fully build your Reavers yet, you can get them built enough to play, but since they are one of the worst units in the game atm, they will get a change.
