I’ll try to address some of the points as I see them, treat it as a loose commentary please:
- Beastmaster - sure, why not.
- Ritual tattooist - just a question, you are aware that we have warpaints in the game, yes…?
- Bard - Nope. I’d just see the “performers” to be slottable to (and expanded upon) the various instruments, as a “(music) crafting stations”.
- Rune Master - not sure if it belongs to the world, besides - some of the Siptah weapons already have (some bugged though…) +heat/cold (protection/application) modifications.
- Servant - as long as it wouldn’t count towards thrall limit we’ve. Could be modelled after the Pippi mod thespians and work as a trade vendor, banker, or just NPC with dialogue/door opener, etc.
Thralls:
- Thrall behaviour - don’t mind that.
- Customizable clothes on station thralls - yes, please.
- Hm, nah - don’t think we need that. Would be better to make all the factions more useful - as for now, if you want a fighter, you go for the CimBer because of the attribute setup & hidden mods - make the stats more in line with the archer/fighter class & make the hidden melee/ranged damage modificators more dependant on the tier (or - just make all T4s from all factions usable - by updating them to the RHTS for archer baseline or CimBer for melee) - and we’ll be good.
- Ammo box - sure, why not. Just allow us to choose the range of it, and/or make the thralls possible to link to specific box.
Gameplay & etc:
- Neutral on that. Would prefere a 1H spear, to be used (historically accurate) with a shield instead.
- Make the legendary actually worth it. Same as with the delving bench ones, as most of them are just not really worth it.
- Pippi already has those (cards, race, not sure about chess).
- Dunno, neutral on that.
Few More Things part:
- & 2.: YES
- Either that, or - like with Pippi - trader/(community) vendor thralls.
Hair, beards & other things part:
Skip, though dual wielding won’t probably happen. Would prefere a way of resetting/respeccing the traits on thralls, to not waste those 6-10 grinding hours just because RNGesus said he doesn’t love me… 
New Building Blocks:
- Placeable trees & plants (aka - proper gardening) - Sure, yes!
- Hm, dunno - maybe? Don’t mind Stygian (would prefere a proper DLC pass though), Lemurian or Giant Kings feel a bit over the top though.
- Sure - and more windows with "crates), maybe Turanian?
Horses:
Just a question - you DO are aware of the modifications to speed/maneuverability/horse stamina use/dmg reduction of the various saddle types, are you?
Regarding that - would be nice to have each cultural saddle “style” come in the 3 present varians, not like the older (Yamatai, Khitan, Turanian) ones - in only 1.
Siege defence:
Don’t really PvP, so will skip on that.
Protective Idols:
are you aware of the “protection bubbles” offered by the religious buildings…?
DLC tools - if they’re as useful as the DLC weapons compared to Siptah weapons, then no - don’t need those.
Capes & cloaks yep, belts - hm, might end up looking quirky - if experience from other games can be used…
Idle animations - sure.
Weapon effects - going to be probably addressed by the weapon camo system in 3.0
Weather storms & others - hm, maybe? As long as it doesn’t damage the base (too much/when away).
Underwater world - dunno, don’t really care about that.
From my side - I’d add some “AC-styled minigame”, where you can assign thralls to perform some tasks/quests - would make a purpouse to actually farm them constantly, and use up in caravans/caravan defense, resource obtaining, etc.
Also, would like to see proper farming, with maybe farming thralls and some way of “need/automate” food production & consumption. If you starve your thralls - they’ll get negative stat bonuses & can eventually die, but if you setup a proper food production chain (whether farming, hunting, gathering or fishing) able to feed them, all will be ok.
