I know, I saw it. And it is really a great idea you had. The idea is good. You are pointing out the issue about the Persians, but we could have the same issue with other civs no? Romans and Germans notably.

I don't know about the leaks and roofer comparison..  About autotrain, the feature wouldn't probably be considered for vanilla integration for good reasons. It introduces technicalities and over 20 buttons each supporting 3 different interactions (scroll, left click, right click..), even if it wasn't that hard to use, it was done too empirically resulting in something that complexify the UI by quite a bit... Which makes it ok as mod, but probably not for vanilla.   Now I've recently proposed a system that offers the similar gameplay improvements, or even more in some areas, by having a very general way to queue production orders. This system currently introduce :  0 New UI elements 0 New hotkey Should-be perfect play-flow No automation feeling, since actions are initiated by user, and no overlay look like pupeting another like with autotrain. This, in my view, this makes it much more likely to be merged into vanilla. But currently I haven't got much feedback, so if you want to contribute on this feel free to do so here.

Sasanian special tech: https://www.wikiwand.com/en/Panjagan - Panjagān was either a projectile weapon or an archery technique used by the aswaran heavy cavalry of the late military of Sasanian Persia, by which a volley of five arrows was shot. No examples of the device have survived, but it is alluded to by later Islamic authors, in particular in their description of the Persian conquest of Yemen, wherein the application of the unknown panjagan was supposedly the deciding factor in Persian victory.     If we can get a "multiple projectile" patch committed ( @real_tabasco_sauce ?), then this could increase the number of projectile their cavalry archers loose per volley. Otherwise, it could be a attack rate tech (fire faster).

Yeah, not to mention the batch training, which also increases the total training time to equal or more than "3x the speed of training" in SC II per batch. Or, you can change the setting in the Options and never be bothered about it again. Oh, and you can also disable the match-setting tips, so you aren't annoyed by that "Medium AI is too hard for beginners" message. Again, the "Normal" AI in AoE2 will destroy any new AoE 2 player, regardless of his/her experience with RTS.
