There is already alot of clicking in this game. Its not a matter of being able to pause or not.I would agree in multiplayer since you cannot pause and have no time to consider, or if you generally like to play it more like RTS even in singleplayer.
But its speed 4 with autopauses on many things. Everthing else is unplayably slow.
On speed 3 i fall asleep waiting for units to arrive on the next province.
I could micro the shot out of everything all the time every day. I can also save my sanity and limit the micro to meaningful things with high payoff.In SP micromanagement is certainly still possible and useful
I dont have a set date.Maybe adding 2 cav should only be considered midgame (say till 1650
At some point after tech 13 i decide that i dont want to deal with 3 unittypes anymore. Depends on the overall flow of the game.
52's is for the beginning of lategame when level 8 forts start appearing and stuff like attrition still matter a bit.I would go for 48/0/48
Later on i just walk around with double 40's after the +3 siege.
The one extra Cannon is to avoid falling to +4 bonus from attrition.
