I didn't said that we need anything like that, if I weren't understandable then so sorry, but I just joked with it. You can react others then just the dancing, I just seasoned the thread's name with a bit of humour (looks like my english skills failed me again). If you addressed the 'cutesy' part directly to me, I don't understand why, I didn't made a 'look I'm a real girl' thread as others on the forum... I'm not even said anything like that (I wrote that's just a joke). I didn't added to my entry post the example of the Dawn of War game's unit movement, for example: - my most favourite in every wh40k case - the eldar banshee's running which is pretty cool (graphics old but I still love that game) so that would be great if the devs should add such different movement animations. And don't worry, I don't think that the devs will add anything that is cute I'm here for the Wh40k feeling too.
Eldar could get away with dancing, I guess. But otherwise there should definitely be flavour emotes to support RP. Salutes, laughs, threatening gestures, prayers, Orkz eating their earwax etc.
