Yeah, like the bow string striking the bow. These are better than the current ones though. The current ones have this weird "woop" sound as if the arrow is swopping past your head.
@Alexandermb's trot animations look great in DE. A little slow [actor animation speed], but the motion is awesome. I'd use it for heroes and heavier/slower/melee cavalry. The existing run in public right now I'd use for my Scout Cavalry and Ranged Cavalry.
Suggestion for the variants.
The trot variant could be base_horse_slow, while the current variant that looks like a slow run could be base_horse_fast. Figured faster ranged/scout/raiding cavalry could use base_horse_fast, while heavier cav units such as champion and hero cav could use base_horse_slow.
While the guys on the right look accurate enough, the ones on the left look like they have some serious Parthian influence. I don't think that's what the Battle of Raphia and Magnesia's Seleucid cataphracts looked like at all.
