Yes, as it has a range from the commander.

Yeah, except the current Sid isn't a viable option as a Force Battery. You bring him in to Pawn people, not charge them up. What I'm looking for is a HoloSid-type FB that'll break the non-Droid Se[s into competitive play.

well we have only seen 2 of 40 pieces, so we may be getting more seps that will benefit from it more.

I would also like to add in Aurra Sing (either variety) for another couple of pieces that may help

and don't forget cade, bh. Thats a scary thought

For AV, there is:
Dash-RS
Bobas (BH rolls a 19 for 60) :)
Jango, JH (something about a 70 on a Jedi that's fun)
Maris Brood (flailing away with a 10% chance of 60 which may render the other 3 misses moot)
Kreia (Dynamic Duo? mentioned on WotC because she has Flurry)

Just bear in mind the cost factor. She is almost 60 points, and most of the usable fleshly's that are available for the seps are also above 40 points or so. So I agree there are some possibilities, but will they be worth it to utilize? Besides this is a CE based on Crit hits, and those are never all that great. Granted it does allow the crit on a 19 as well, but again, she's in a droid faction why doesn't this help droids? We've seen her boss them around now on a few occassions.

Well, I feel between the the living Seps and Fringe followers capable of making multiple attacks, there are quite a few options. It's not game-changing as it is so luck based, but fun?

As to the Droids not getting any love with this CE, they got enough with GGDAC. Lancers are scary enough as it is

I wouldn't be surprised if we see a Sep commander that makes allied CE's affect droids if they already don't.

Fun pieces, yes, but not much more than that. Rex's CE is not that different from one of Clone Commander Gree's effects (and Gree has multiples) since Gree's is rangeless and Rex requires order 66 while Gree requires Trooper or Soldier and Follower. Unless you are running Scorches (not Sevs since they do not move much), go with CC Gree if you want the CE. If you want damage output, go with the old Rex, who only loses 10 damage, 10 hp, 1 attack, and Flight while gaining 1 defense and the ever-important Twin while costing 8 points less.

As for Asajj,she gains too little and loses too much in comparison to her CS version to be worthwhile, especially for the cost:

+ 23 points
+20 HP
-1 Defense
-1 attack
- Loner
+ Twin
+ Evade
+ Niman
+ 1 Force
- Riposte
+ Master Speed
+ Sith Rage
+ Grip 1
+ CE grants Vicious Attack

Since Mouse Droids solve the contradiction problem with the old Asajj, I feel this one really does not add much as an improvement. Granted, it is a step up, but an expensive one. The old Asajj could attack twice at 16 attack. This one attacks four times at a 13 attack. Asajj SA attacks at least 4 times at 16 attack (more from rolling cleave).

If you want a crit based commander, go with CS Asajj. This one is too expensive. If you want an effective attacker, go with Asajj SA. This one is too inaccurate. If you want a piece that can do both, or a BBSV (to give Asajj SA Evade) won't synergize with the rest of your squad, this one is your best bet.

One last note: This Asajj is more expensive than any existing Dooku. Could this be a sign we are finally getting a Dooku with a CE?
