Journey Guide Relic Delta

I just finished my grind for Starkiller requirements. I blew past the first four phases, but I keep getting demolished on the final mission. It’s not quite fair that I’m having to deal with relic delta in a mission where the game gives me a character to use by default. I know this isn’t the only mission gives characters by default. Can we please increase the level of these characters ASAP to make these missions playable again? It would be even worse if someone new bought a LSB only to not be able to attain the character they were interested in due to the game not being beatable
