Why is there no option to leave it as-is? The results get misconstructed by doing it this way, as it only accepts answers that are do want it to change, which I doubt reflects the majority opinion.
Why should it be buffed ? And up to +2/+1 armour would be massive, for an unit already quite good at what it is (notably a trashbuster), plus would unbalance civs with and without gambeson…
Not far enough, give the militia line the base armour of the elite teutonic knight, pierce armour similar to rams, and auto-healing like berserks. Now it’s balanced
Someone who unironically suggests +2/+2 armor cannot be someone with relevant experience in the game. We are talking of making Militia-line better than Serjeant, both stats- and cost-wise.
Gambesons is fine as it is. Knights and certain “too fast” civs like Mongols, perhaps Mayans need nerfs, Crossbow needs to be a bit more meta, and then the game will feel good again. Paradoxically, it’s the best time ever to be a Longsword, since we’re essentially in a Knights meta.
