They did great on all parts, as extra activations/grabbers/door openers or to block LoS. Ability to trade into extra block often lets them survive an attack. As for eClaw, he probably not worth 6pts but it is an amazing figure, i really like him. Tried regular at first, but the conspire surges become too inconsistent, and he needs focus to hit anything decently. On the other hand elite can do just fine on his own. Even did some focused scout shot on 1st round, as he hits 10-12 range pretty easy. And since there were many empire players its also good to bait zillo exaust with scout so that vinto can go in and do his pierce+bleed surge later in the round. The drawback on elite is that you really dont want to take much dmg with inteligence leak because it becomes way easier to one shot him. I also had to get rid of strategic shift because i want him to be attacking instead of using his whole activation for the shift.
Dealing with with vader is pretty easy, there are several sources of unmitigated dmg in my list. I think the worst match up is IG since he has assault, blaze and doesnt need to get as close as vader. And han, well, i either ignore him or try set up some shooting places so i dont get return fire.
