No you couldn't tell me anything because combat is broken, diplomacy is broken, THE AI is BROKEN! So take your passive agressive attitude and shove it.
that's not objective and fair, it's highly emotionally base unfair judgement. Just because you couldn't handle the battle that does not mean the combat is broken. I able to manage to capture a highly fortified Rome with huge defender in melee, archer and mounted unit using Greece civilization, I did that with equal military technology without any horse support. It took awful amount of effort and time, as it is should be (not simply put your catapult to suicidal mode and bash the hell out of it). Quantity without organizing your troops and proper strategy will not work on this mods, you need to read the description of each unit and use it strategically.
As for diplomacy, enabling vassal state will give you more diplomacy, it will divide nations to factions and AI will think twice to declare war on one and another, it will wait till the right time to strike (like when it is weaken, or when it is get attacked by multiple civilization) it is more realistic that way.
Even though this mod is not perfect, but it is simply the best mod, I simply can't play vanila anymore after knowing this mods, the stack system is awesome, the ability to bombard enemy unit, no more suicidal siege weapon which are dumb down the strategy so badly, no more stupid technology trading, awesome unique unit and building, and very stable mods without crashing you just need to install and play without altering anything, and many more (which can be endless if I spell it one by one). But it is indeed need improvement not because it is not good but it has a potential to become much better.
Not all religions behave equally in terms of heath, economic opportunity, and political will. In RI, Islam has many advantages that other religions do not, such as converting cities by conquest and their Mujahideen are a powerful early unit. I also think (unless I'm mistaken that Islamic Temples have +1 to trade routes as well).
My strategy is highly isolationist in this mod because of my base strategies are science and money. While open border highly advantage my city razing rival, hence building Islamic temple somehow dictate my playing style. IMHO it is either decrease on technology transfer on open border to 20 percent perhaps? and enabling research agreement later on (50-75) or basing technology transfer from open border which amount referencing on current relation (friendly=max, please=high, cautious=moderate, annoyed=low, furious=very low).
However you made a good point regarding Islam spread by conquest.
