I'm more for adding multitudes of insigna (for eg. the the various airborne insgna etc), or the variant between the panzergranadier, farshirm, SS and werhmartch uniform. The Swatstika is really a small deal, and sadly, there are folks out there who see the need to recall 'glorious nazism' once we give a hint that it isn't all that bad a symbol, and no one should give that crap about it being a buddhist symbol either
I really advocate for the hand signs, and from the 3rd and 1st person view of the scout calling for arty without looking through the binocs, I know it is possible, but yer, yer, it IS going to be a real load.
To make it possible at all, the devs COULD add 1 or 2 of such extended animations with each release, so that by say, the 7th release there would be some significant 3rd person animations.... And nothing as ridiculous as saluting, no.... Maybe a fist up to signifiy 'hold', the same scout animation can be used for 'go, go, go', just repeatitive and faster and pointing at the eyes followed by pointing in a direction would signify 'enemy spotted'.
If workload was not a problem and we could jsut imagine all the animations possible for commands in, well, I think we would be having a game with some SERIOUS immersions. Imagine for instance, there was a way of whispering, say by using minus and plus to change voice level from shout, to talk to whisper and finally to no sound, then the hand signals would really be tres cool in a special ops mission, where the element of surprise is paramount
What is more, hand signals could aid in suppression and flank tactics. 'Cover fire' would be accompanied in 1st and 3rd person by an animation similar to that in BIA (side-truned fist pounding the air in the direction of the enemy), 'go, go, go' as already stated, 'fall back' etc.... And perhasp bots that follow your exact words as in terms of where to move and how to suppress. Personally, if a few were to be done with each version release, I'd say those particular ones 'suppress', 'hold', 'go, go, go' and 'take cover' (represented by holding the helmet, facing downward and slgihtly looking back) should be top on the list
But these are fair dreams by people who don't mod... so pardon our crass requests....
