Worst possible change they could have made.
The ICONs go very dark blue for 3/4 of the GCD and then immediatly go very Dark again if you click anything else.
You have .25 of a second to spot the right darkish ICON and then hope to find the next one.
How the HEll did this make it through testing ?
For me its damn near unplayable like this...my eyes are burning after 30 minutes....
Three strikes your OUT !!
THIS:
OLD UI: Buttons DO NOT get greyed out during GCD, you could tell what abilities you could use once GCD ends
NEW UI: ALL buttons get greyed out during GCD so you cannot tell which abilitiy is greyed out because of GCD and which is greyed out because of lack of power/too much heat.
This makes it impossible to plan ahead.
