Units introduction and Revolution option needs UPDATE!

I just mentioned, many units have been repeated, its really made so much unnecessary chaos.
We should have new “Revolution Units”, “Treasure Guardian” and “Outlaw” branches in the introduction to prevent mistake and repeated like AOE2 since DE launched!
Let me say again:
If you have SIMILAR NEW ONE, just REMOVE OLD ONE!

Also since minor civ became playable, the developers use NEW minor to replace it.
I don’t understand, WHY NOT follow the example with Revolution option to prevent mistake and awkward at same time???

Finally, it’s really not hard to find how was the bayonet looking before modern bayonet…
These just part of it, we really need small change these units model…
