The new GCD UI is horrid. Take away the greying out option. You wanna grey out something on CD fine, but leave the other buttons alone.
My only issue is, while GCD is in effect EVERYTHING is greyed out and there is a delay on the greying out, it makes everything confusing. Now we have black, grey, blue, flashing, why don't you add a chicken noise, 4 different bells, a foghorn, rainbows and purple horseshoes while you are at it?
If it isn't broken don't fix it. How about you fix the million other things wrong with the game before tackling something that isn't broken.
FFS.
