Also out of curiosity, currently if someone isn't exclusively a fire main grid user for example, how well is that person doing right now against the disaster wind ragna? I'd actually be really interested to see a video or screenshot or something of anyone solo'ing the disaster ragna with an off-element team/grid. Would definitely pique my curiosity.
But sure since it's a raid, one can always request help. But that means one needs help to begin with.
And in the end, when players are using 2 grids of equal strength (let's say both are maxed grids) the ones using fire against this current wind ragna, or w/e has ele adv over what they face will always out damage the ones using off-element. Thus they will get the MVPs. Thus they get more mats, 5 frags instead of 2 for example. Thus they can farm w/e it is that they farm faster, like soul weapons. Easier. More efficiently.
