True, and the lack of stands (or stands phasing in/out/in/out of the line anyway) doesn't help then either. Would've been nice during a run of stands that we got a more sturdy droid. I'd think at some point they'd even consider some small "foot pod" type stands as an accessory to a new battledroid...
Still though, even if a battledroid does or doesn't have knee articulation, the issue with the feet is a problem. The current 2-pack droids fall over and they have barely any articulation, the ROTS droids fell over as did the Saga sculpt... Technically, actually, the best droids were 2 or 3 sculpts that had knee joints... E1, Boomer Damage, and Security are all I think the finest BD's they have made, and they've all got some kind of knee articulation.
I'd dig it if they just gave us very nicely articulated battledroids and included stands then because the figure's design just demands it. Kind of like the waitress droid or whatnot. Much like Clones, one sculpt would go a long, long way with this figure.
