I think this is the best solution. Just make sure that both grenadier and mortar have some disadvantage compared to Cannon, or that mortar comes around the same time as artillery.maybe archer -> crossbowman -> grenadier -> mortar -> modern/mechanized/whatever mortar?
Can you guys think of a better unit to lead from Crossbow - Mortar?
ranged to melee
Maybe a solution to the problem of promotions being useless in upgrades would be to separate out the Accuracy/Barrage promotion lines from the Drill/Shock lines and have one lot convert freely to the other when swapping from ranged to melee. So a Crossbowman with Barrage 1 would upgrade to a Rifleman with Drill 1.
The Simpler option might be
Give Riflemen+Infantry a range of 1
Also the battles of this time primary were fought between two armies lining up and then shooting at each other. It wasn't ranged fighting per-say, like it was in the earlier eras.
I think a guy throwing grenades over a 2 tiles, or over a mountain if he got the promotion is just to unrealistic for me. I'm not for it being 100% accurate but I think that is to far fetched.
And so you think Arrows being fired across mountains and battleships shooting over mountains is? And not to mention the GDR
That probably would be the best.
Logistics<-> Blitz
Range... (no equivalent)
Give Riflemen+Infantry a range of 1
