Is there any balance reason as to why you can't see the second yellow trinket charging?
Maybe I'm blind and I haven't seen it, but it has always annoyed me that, sure, yellow trinket works on 2 charges, and if you have one ward available the second is reloading in the background, but there's no way to see how much time is left before it charges up unless you use up the one you have currently (as it then enters "cooldown" mode and shows the timer.)
Is there any reason for this, is it an oversight, am I blind, or there's something wrong with my HUD?

doesn't show number of wards placed already on map?
