The real damage in the team you're suggesting is ony done by Rey. As Barris and Lumi don't bring her back and Daka is not a guaranteed revive, the damage is gone once Rey is one-shotted. Also with a stunned RG and focussed Rey it's a game over.
And yes, RG is a good protection and help your team to breath a little. But maybe still not enough damage to win the fight with Lumi and Barris.
The actual meta dictates that you need heavy dmg critters to win the fight. The update may change this as the devs are planning to prolong the fights and give defense a chance.
Until that it's speed, damage, more speed, damage, more damage, speed... :smiley:
