Troops and Cav Line of Sight
For example if u are fighting a guy with Smelter (Cavalry) Granary (Troops) los upgrades vs no upgrades does this affect the battle. I normally dont get these upgades unless i have a load of resources to hand.
No, but you should get them anyway (unless you're playing aggressive). Big mistake if you don't get medicine especially, even with two raxes you sometimes can't build army fast enough. Research both lines and you can prepare a lot better for attacks.
I don't usually bother w/ the smelter upgrade until the late game as my limit w/ cav is typically resources (not training time). I often get the medicine line in GP if I'm skirmishing, I've retreated & I want my troops to heal faster.
I usually research the medicine techs sometime in the game because they help you heal (the first one gives you 2x healing over the base rate I think).
Construction line can be important too if you're booming with a small army.
I get forage late med or early gp to increase despot/monarch radius and craft; also 5-10% more hp.
Can't wait for Humble to show up and fight with Div, GG.
What have I started? shock
Humble isn't stupid, I'm sure he would see that medicine is better than three raxes. ;)
Anything that improves ur armies and gives u a small edge is worth it if not too expensive - certainly Herbal Lore (los(think ranged units)+creation speed+garrison healing) and forage(anti-attrit+radius for supply wagons and, more importantly Despots/Monarchs) are worth it when uve got some spare coin.
