Yes i see what you are saying about the archon, i may as well make him the warlord and try get more CP, something that this is lacking.
With regards to making it a batallion, it was something i considered but to do this i would need to take away from my Anti-tank, something the DE are really lacking.
This it self wouldnt be too bad but i am having to pay around 200pts for units that would be useless. What does adding another archon and 3 units of warriors give me other than CP.
I could drop the beasts and do this but i actually think the beasts would be better.
