I will never understand why people want this, Sure, it would be good for a singelplayer game. But if this game (wich i hope) will come to a competative stage, stuff like this will ruin it for new players. When i play a pvp game agains someone, i want MY skill to matter, how i micro my units, and how good i counter his troops. With a equipment system, it will just make it way to advanced for you to enjou casualy.
What they need is more "skills/attributes", so you can customise your units more that way, wich i think that they will. But once again, equipments AND "skills/attributes" will just be to much customisation.
Being able to somewhat customise the collor of troops would be nice though.
