I've had quite a lot of people in my games misread a play because they dont think an enemy has their ult (5/6 or 6/7 charges), despite them picking up a frag or possibly grabbing ult orb. I've been told by a lot of people in game that the ultimate counter for the enemies updates throughout the round, but this is just plain not true. Same goes for money, you get all the updated information at the beginning of the round, but you don't see their money go down when they buy. Keep this in mind during your games and good luck!
