I'm just a bit disappointed, that it takes 12 seconds for the ephemera to actually show it's full effect. You're practicly never going to see it during the mission. The only time you see it, is when you're afk in a city or in your orbiter. I can understand that it doesn't show it's full effect instantly but 12 seconds is just absolutely ridiculous for a fast paced shooter like warframe. It should be 3 seconds in my opinion.
That you can't color the golden parts is just the icing on the cake
