just stood there in org with my rogue and pressed Z to get my weapons. Right after I got them out I pressed my mount, my weapons stayed out when I mounted and same when I unmounted and did any emote like dance or charge.
I wanted to check if it wasn't just some wierd bug or someting but it happned again. All you have to do it so press z and then then mount while your char is pulling his or hers weapon(s) this have to be done quick. very useless but looks good no idea if other players sees it though
just a fun thing to know i guess wish i could post a screenshot but i'm really noob at that could try later though
