Hi, I have been playing the RI for quite a while (since version 3.4). However, there are a few "imbalances" that have been bugging me:
1. For Line Infantry and Light Infantry, the 100% vs Melee seems a bit excessive. In the Renaissance, Melee Infantry still has a role in defending against cavalry and assaulting cities (Arquebusiers only has a +50% attack vs Melee, but not defense). This means racing to Flintlock Musket gives an overly massive military advantage. Maybe the bonus should be scaled instead (i.e. Line Infantry +25% vs Melee, Rifleman +50% vs Melee, Trench Infantry +100% vs Melee)? Also, Longbowman in cities tends to perform very well even against Rifleman. Maybe there should be some bonus against archers?
2. For the "Heavy Cavalry" line, would it be better if the +25% vs Melee is changed to +25% attack vs Melee (or +10% vs Melee & +15% attack vs Melee)? I often find that enemy Cataphracts and Knights in cities will beat my veteran Man-at-Arms because the combat odds skew in their favor. Also, I find that Spearman/Pikeman often significantly underperforms against heavy cavalry because of this bonus. While I get that they are not supposed to beat cavalry 1-on-1, I should at least be able to counterattack wounded Cataphracts with Spearman under favorable odds.
3. Special Forces being classified as Gunpowder instead of Recon seems weird. IRL, Special Forces are mostly used for infiltration and recon missions. Would it be better if it is reassigned to Recon?
4. The War of Attrition doctrine may need to nerf its bonus vs Melee (or introduce some other nerfs)? While doctrines are supposed to be powerful, this doctrine in particular feels overpowered. It basically shuts down enemy Melee altogether and invalidates Spearman/Pikeman as counters against Cavalry. Looking at the other doctrines in Classical Age, Rites-of-Passage is highly conditional on the terrain, and Imperial Glory offers moderate bonus over Combat promotions. War of Attrition just seems out of place in how much of an advantage it offers in the early game.
5. Specific to the Turks, the Janissary UU seems strictly inferior compared to their Line Infantry. However, they are unlocked by Absolutism, a tech that cost the same as Flintlock Musket. Either they should be buffed as an alternative to Line Infantry, or they should be unlocked earlier and their strength rescaled accordingly (maybe at Administration?).
