Wish you a good recovery, Callum. I have played warband multiplayer for about 2k hours so if you don't mind some judgement, here's mine:
1) Τhe game's speed feels strange. Movement and attacking looks like dancing around instead of fighting. Τhis might be because the animations themselves seem a bit strange and a bit robotic in my opinion and lacking that 'punch' that a warrior would have when fighting for his life.
2) The sound environment needs more and different sounds, in many cases the game feels very void regarding sound and empty, and then you hear 10 'UH AH!' in a row. It needs more variety and some battle class background noise which remains constant.
3) The combo system looks very good and if I understand correctly, it can trigger when you hit an enemy, allowing you to deal extra damage really quick.
4) Αrchery seems like a big issue. Not only they get the crosshair which is immensely unrealistic for a medieval game but it seems like shooting arrows is very arcade-like, which velocity playing a much less impact than warband. This is the impression I get from this video. If that's the case then I hope it gets looked at, because aim and shooting in a complex melee game should not be the most efficient of dealing damage, but should more of support and pressure. It almost feels like a different game at the moment, again from the video.
5) Removable or not from the hud, points should not be placed upon your character in any form or shape when we talk about a competitive game that timing and visibility has so much to do with the criteria of you winning a fight. Big no.
6) Regarding leg movement animations, there's a big desync on ground covering and actual feet moving animations. Some characters feel like they float, because they moonwalk with relatively slow movement on legs and cover distance fast, which looks like high ping. I imagine this is not the case in that video though.
7) Classes seem, still, underwhelming. This is something I would need to test, but nothing was memorable regarding characters and playstyles in that video. It could be the nature of everyone being relatively new to the game, but still.
