Go over every avenue of power growth in this game and consider how applicable it is to a particular idea. Sooner or later you think about Assault skills. Then you realize that there's a finite X number of Assault skills equipped at once that eventually have to be divided up three ways for a tri-element strategy. You'd only have to divide your weapon grid in half in a dual-element strategy, or not divide at all in a single element strategy.
The value in multi-element buffs is when the gacha hates you and you don't even have the pieces to run single element in the first place. Or if you can't even fully run dual-element yet. When your concern is more about the floor than the ceiling.
