Essentially, the same queue-ing system for abilities and tactics is in place. The GUI, however, is gone to something more subtle: for tactics, instead of W A S D to pick the next round, you click the tactic on your hotbar, and then the relevant hit/miss is in system chat. For abilities, you click an ability on your hotbar, and it begins to blink (this is where it used to go into a box and wait). When the blinking stops, it turns solid red (where it used to move into the next box), and either flashes a green circle (you hit) or a red cloud (you missed).
