Behold, the example of heavy armor upgrade of Isengard warg riders!

As the result of implementing such a system, all units that have an option to be upgraded with something of better quality, will leave their barracks or a respective building in more simple clothing, just chainmail armor or leather in some cases. But once upgraded, units will receive helmets, additional layer of clothing and sometimes even more, depending on the exact unit. In case with these warg riders they leave warg cages without leather armor. Tough leather armor will make them visually different and much more durable in battle!
We know that this might confuse many players at first, as no armor will ever glow as it used to be, yet we think a lot about the efficiency of the system, perhaps, we will add a possibility to see, if units are upgraded with a single sweep of a mouse above the unit or something similarly simple. You also may think that this idea is too much for an RTS game, yet a very successful real strategy game offers such a system, it's StarCraft II, and it's even an e-sport discipline! And after all, our artists will try their best to make very distinctive looks, so any upgrades won't confuse players at all!
We want to ask you, if you like the idea of the new system or not. Or if you have even better ideas, ready to be shared! Choose any of the options above in the poll, share your thoughts about this!
