XI also had a lot less input from the user. In XIV input is given every 2.5 seconds about, or 3.5 if you're a mage. Where as with XI, input was giving maybe every 30 seconds, 45 seconds, and then maybe 5-10 second if you were a mage. So it's hard to really say that SC/MB "coordination" was all that hard cause the reality it that system was just a waiting game for everyone to be ready to do an ultimate attack and in the end was easy enough to pull off because you didn't have much more responsibility than to do burst dmg.
