The king's job is to command their peerage and utilize their servants in the best way possible. You are mainly thinking about the basic Rating Game where the objective is to defeat the opposing king and where all of them are fighting on the same field. And you say that Issei's team won't become as powerful as Sairaorg's or Vali's? What is stopping Issei and everyone else from getting more powerful? Asia? Issei and the others have been getting more powerful while Asia was in Rias' peerage. And Phenex Tears are able to be used. A king's job is to utilize his servants in the most effective way possible. That includes Asia although she is not a combatant. A king's job is to think of strategies for different things in Rating Games. That includes thinking of the best way to protect your healer and utilize her in the best way possible. Having Asia gives him an edge up on other teams. He has unlimited healing while almost everyone else has to rely on Phenex Tears. And that will make Asia a prime target. And Issei will have to think of ways to use her in the best way possible while having her defended. That is one of his duties as king. It's not just to have powerful servants and telling them to go out and crush the enemy, but utilizing his servants in effective ways. For example, in Volume 14, Sona used Issei as a support type since he couldn't don his scalemail and we saw how effective she was. Saying it's a burden on Issei is an insult to him because that implies that Issei is not strong enough or bright enough to have Asia in his peerage.
