UI changes in latest patch make the game harder (May 5th)

There are two kinds of changes I found so far –

1. Minimap icons for some objects were changed to generic blobs.
   Towers on minimap are blobs, wards are blobs. They now look the same as allied couriers or techies mines. You now can't tell a sentry ward from observer ward.
2. Some units/buildings lost their "selection circle".
   Creeps don't have a circle (when you hover mouse), making it subjectively harder to last hit. Towers don't have "attack" circle (when you hover holding Alt), making it harder to avoid being attacked or place vision (yeah, I know that attack and vision ranges aren't the same for tower, still the circle is an indicator of sorts for warding)

I can't imagine what could have driven these changes apart from "lets make the game simpler", but it seems to have misfired horribly, IMHO.
