So Im playing a Rigger, quite fun with the drones, and I currently have 2 of them. I opened up a fourth weapon slot for a third drone (class S whenever I can buy it) but during combat I just noticed that for every drone active you lose action points for your Rigger. So with only 2 action points, I can only have 2 Drones active (and I cant shoot myself, but thats ok for now).

So is there a karma talent that increases your AP pool that im missing, or am I boned? And if so, side question, can you respec? I could sware I saw some sort of respec button on a vendor but now i cant find it

Your character will eventually gain Action Pool Points at various milestones in the main story. Additionally, one of the drugs in-game (Nitro, I think) temporarily gives you +1 AP, certain shamans such as Shannon Half-Sky can caste Haste which grants an additional AP, and certain Alpha-grade Cyberware also grants bonuses to AP (Wired Reflexes).

I knew about the temporary boosts. So you DO get more AP from the story you say? interesting

Yep -- without spoiling anything, you get a permanent AP gain for finding the identity of Sam's killer, and another after completing the next story milestone about two hours from there.

I missed the second part of your question from before, but there is no Respec (that I know of) in the game. What you saw on the vendor screen was "Revert", which cancels your purchase orders before you commit to them. Yeah, it's a weird word choice. :b
