I agree you get better return from seniors, which is why everybody wants to hire seniors. But we get new seniors by training juniors/letting them get experience. I think 5 juniors + 1 senior isn’t the way to do it, you should have at least 1 senior per junior (better still more seniors than juniors). Then you still get stuff done (maybe a bit less than if you didn’t have the juniors) and a few years later you have a couple new useful intermediate developers (and a few years after that they’ll be experienced seniors).
