Cid is a pretty easy and simple fight, the only things really that justifies explaining is him having 3(technically 4) different versions T.G. Holy Blade, and his Crush Armor tether...
Everything else is old mechanics, some from Ozma and some from Rabanastre, which people who are at the Monastery have had to do.
And people should be able to pay attention to other party members enough to see them moving close or away from the boss, or off a platform.
