For me it's probably the PartyScreenEnhancements and the RTS camera. The first one ads just a few buttons that let you halve the time you spend in the menus doing basic stuff like upgrading troops, the other one is a dramatic improvement to battles as it allows you to both pause the game and use an RTS-type camera to observe the batttle from the sky, which in combination let you actually order troops around during battles AND fight in them at the same time without insane micromanagement.
- Fast Dialogue
Also the new dialogue cut scenes look terrible, miss the fully rendered ones so much. Stuff like this really makes me question TW's development. Everything like immersion or convenience always gets sacrificed to always "eh make it work, sort of"
Bad (nice trees huh?):
Good (isn't it amazing I can just attack?):
To put it simply: "Just let me kill people dammit!" - Rex Power Colt
- Realistic Battle Mod
Armor in the base in game is terrible. It either provides virtually no protection or makes you nigh immune to low damage output, once you get it high enough. The way protection works need to be seriously re-worked. RBM isn't perfect, but it's a much more enjoyable experience if for no other reason than battles aren't over in 30 seconds. Everything dies so fast in the base game that if you get distracted for even a few seconds, an entire 100+ man formation gets wiped out.
Battles need to last longer, especially when it comes to armored infantry. Obviously Looters should fall pretty easily, but when it's armored infantry like Legionaries vs Vlandian Sergeants - that should be a slow slugging match that lasts a few minutes.
Armor has to be worth something. The weight and cost are rarely ever that beneficial.
- Party Screen Enhancements
Just let us sort units, it's ridiculous nothing like this is in the base game yet. All you really need is like 3 filters Culture, Tier, and Type. That alone would be something.
- RTS Camera
Having an additional "eagle perspective" zoomed out camera mode would be nice. Also it's damn near impossible to see unit pips in the dark, is it asking too much for a color the player can see? Outlines are also very nice - especially in forests.
But perhaps the most important? The ability to have your formation attack another formation specifically. This just such another no-brainer that should be in base game. And yet we have useless formation commands like "Column" which probably no one ever uses. I feel like the people who make this game don't even play it. But nope just F1 + F3 and watch your units just spread out in the most idiotic manner.
- Party AI and Overhaul Commands
Once again; is it really asking that much to have some control over Parties? Why can't I just have a Party patrol a specific fief to keep it safe from Raids, etc. ? Or why can't we give Armies orders as a Faction Leader to again attack/defend a particular Castle/Town?
