Hiw many CPs do we actually need?

I'm building a list for a local tournament, and noticed that I was instinctively aiming to fill a battalion detachment. In my case, that means I'd end up fielding 2 Archons, which seems like a questionable investment. Because really, I find myself asking how important command points are to Druchari in their current form--considering we only have 1 unique stratagem right now.

How many CPs do you usually aim for?

And which strategems do you spend them on?

You'll need stratagems for rerolls (damage of Dark lances, or Reapers shots if you play them), and deepstriking.
Considering you can only spend 1 CP per shooting phase on a reroll, having 3-4 dedicated to that is enough.

So 5-6 is enough for Dark Eldar ATM. Moral auto-pass doesn't concern you if you don't play beastspam, and counteroffensive is situationnal and VERY expensive (it can be deadly, though).
So basically, spend the points on your DS, then use the rest to optimize your DL damage rolls.

Avoid the Battalion if you're not playing massiveky on the Archon Court. You don't need those HQ nor the CP.

As said early right now we are mostly using a command reroll so we don't need many right now. I do not however like playing with less than 6 in a 2000 point match.

When the codex comes out and we have stratagems to work with I'm thinking 9-12 will be handy. Even though currently our HQs do not contribute to much they are relatively cheap compared to many factions so which could be handy. Kabalite Warriors are cheap as well. Taking wyches via webway portal drops their points cost due to having a delivery method and having footslogging wracks screening haemonculous on foot could work. Really there's not enough info on the codex yet to speculate to far.

Thanks guys. It's an 1850 local tournament, nothing too intense. I'll most likely drop the battalion detachment, unless our codex releases in the next 2 weeks somehow. The more I think about it, the more I find myself gravitating towards more DLs--vs more rerolls.
