There’s warhammer world where tiniest details exist (shown or told), or we extrapolate these tiny details from known rules/lore of warhammer world. Its objectively measurable how accurate something in a game is to that world.
Whats important and not important - can only be said in the context of the game, a product.
Important and objective examples ingame are:
longsword riposte - the sword position while you charge is a legit guard position that protects you, and the strike afterwards is a realistic transition from this stance.
halberd old moveset - a lot of 2-strike combos are a sweep into stab, or chop into stab (still exists). Heavy sweep -> Light stab. Heavy sweep -> Heavy stab. Light sweep -> Heavy stab. Its a very natural & effective 2 strike combo of halberd irl. Remember the video on techniques i shared? It had them, and there’s a second video with sparring, where its used prominently - first strike (sweep) to knock opponent weapon off, then stab him.
But after the patch, these are removed, and the heavy sweep is tightly chained to light sweep which is the thing i hate now.
1h mace (and 1h axe) - in Verm 1 they had straight vertical overhead animations, in Verm 2 they made to be going more from the shoulder - and when you do one after another you alternate between sides - it looks more realistic and effective, than in the 1st game.
