First I want to menion that I don’t think the Game needs commonly shared new trash units. The base ones we have are fine.
Nevertheless I could think about “regional” or “shared” new trash units that are only available to a few civs that they fit.
The new trashs are generally deigned that they counter specific unit comps some Civs have trouble with and also synergize well with Gold units that currently don’t have a natural composition partner. In my opinion especially the latter one is crucial for a trash unit to be viable.
Trash Infantry with High HP, considerable amount of armor but low attack (potentially small bonus vs eagles + buildings)
Role: Damage soaker in pure infantry comps. Like a mini-huskarl in terms of tankyness against archery but ofc not that tanky against archery, but probably a bit more tanky against everything else. Counters knight/skirm comp.
Available to: Itailians, Teutons, Celts, Slavs, Sicilians, Vikings, Bulgarians, (Turks)
Trash Archer with reduced range and bonus vs infantry. Has also a considerable amount of Melee armor. Like a mini-slinger, but less versatile. Good against infantry floods and synergizes kinda well with Camel/Siege. Moves considerably faster than other foot archers to keep track.
Available to: Tatars, Chinese, Hindustanis, Khmer, Japanese, Cumans, Saracens, Ethiopians
Inspired by my trash version of the ratha. Very fast moving, high firing Chariot unit with bonus against Monks, Camels and Pikes in ranged and bonus vs Siege when in melee. Same range as Archers, but very low pierce attack. Counters Pike/Monk/Siege comps and synergizes well with Elephants.
Available to: Bengalis, Khmer, Malay, Burmese, Persians (Dravidians)
Genitour (yes that name)
Ranged Melee light cavalry with same range as Cav Archers. Fires considerably fast but with low damage. Deals small bonus damage vs cavalry and cavalry archers. Counters the Cav Archer/Hussar Comp. Intended to synergize with a comp of overhauled Hand Cannoneer, adjusted Scorpions and Monks. This makes a very micro intensive combo of units that are designed to control several important spots of the map at once.
Available to: Portuguese, Spanish, Malians + Saracens
I am still working on the exact designs of the units and will post them when I think I have them done. I hope that I also get some Feedback here that I can put in my thoughts + creative Ideas.
