What's wrong with XIVCombo? Abilities that don't create choice aren't interesting. Static 1-2-3 combos aren't interesting. You never deviate from them. There is no scenario where you'd go from 2 back to 1, unless the combo proc fell off. Pressing them in order is barely "skill". By all means, have 1-2-3 combos if you wish for animation variety...but why devote hotbar real estate to them? Skill expression is way more interesting than dead, unidirectional, one-dimensional flowcharts.
