1. Italians getting Halberdier would be OP IMO, like if Saracens get Halberdier is OP since they get Mamelukes + Camels + Zealotry. Genoese X-bowmen can effectively counter 2 of the most powerful units in the game Mangudai and Mamelukes something Halberdiers can't counter because of hit & run. Maybe giving Squires to Italians wouldn't hurt I guess.
2. A perfect solution would be to give camel-line as another classification apart from ships so Heated Shots doesn't affect them, have building attack bonus vs camel-line kept but slighty reduced, give camel-line +1 attack (Camel 6/Heavy Camel 8/Imperial Camel 10 attack)so camel-line can raid a bit better(especially for Indians since they have no Knight-line) and are a distinctly better than spear-line infantry when it comes their normal attack since camel-line cost much more than spear-line infantry yet attack is similarly close(Camel 5/Heavy Camel 7 attack compared to Pikeman 4/Halberdier 6 attack).
3. I don't think it's possible, all secondary UUs require Castles(e.g. Longboats, Turtle Ships, Missionaries) besides Incas have Castles that costs 15% less.
4. True Magyars are unmatchable in a 1v1 late game trash war.
5. Increasing the Slavic farming bonus to 20% or 25% would make it noticeable.
