Regarding the tooltips, I don't know the specific settings for controller, but I do know many of the main combos are very non-telling.
They just say

1. - Random skill name
2. - Random skill name
3. - Random skill name

to tell you that button rotates between the three of them, but it doesn't always tell you what these three random skills actually do. If you know the original job, some might seem familiar, but that's rarely always the case. So "read your tooltips" might be a good idea for the usual jobs, but not so much for solo duties where the tooltips say fairly little to begin with. And knowing what the skills do is no help if your disability limits your reaction time or movement under pressure etc.
