It is crucial. Without Hit Material, DEX and units are the only ways to fill the gap between your level 200 ATA and the cap, and having to equip 4 arm units at level 200 to max your ATA is a terrible use of your slots. The only reason to not have DEX is if you're making a pure MIND mag for a Force who's going to be nuking exclusively.
