Separating the buttons would make it a nightmare to play. The basic combo is actually extremely static like dragoon. The only real choice you get is the first 3 buttons you press. After that the whole rotation is 12 gcds before it loops back. Because of the way the finisher buffs works. It buffs in a sequence with alternating positionals, which is also why your second button alternates. So the sequence for your 3rd button is this. 2 , 1 , 1 , 2. Now add the alternating 2nd button, 2 - 2, 1 - 1, 2 - 1, 1 - 2. Now we add the 1st button and your full 12 gcd rotation looks like this. 2 - 2 - 2, 1 - 1 - 1, 1 - 2 - 1, 1 - 1 -2.
