Well, lol. "better" might depend on which side you are on, perhaps i should say better death animations, or more visual.
I'm just somewhat tired of every soldier in a group fading away so fast when they die that they dont even have time to end their death animation!
Having squads just magically fade out the dead numbers, oh i mean soldiers (sorry, easy to lose immersion), is just so utterly dull that it makes combat just feel like a numbers game, like a die roll.
All i want is for some Visual goodies (no gameplay changes requested here, just visuals), something to suspend my disbelief and immerse me into the world, show me soldiers flying back, show me soldiers dying and their corpses slowly rotting down into the ground (if you HAVE TO remove them mid-combat, even though the corpses really should be permanent, if the game can handle them the first 5 turns, why not just leave the models in the memory, theres no new soldiers entering the battle anyway).
Show me anything to indicate that the soldiers are dying and fighting for their lives, not just fading away as if it was a game of chess.
