Maraxis' science is built around quality, as wyrm containment cells and salt are made in Hydro Plants, but because you also need tech cards this makes 50% of your output effectively useless as you can't make quality tech cards with the same ratio, requiring significantly higher inputs to reach the same output without Krastorio 2. This can be fixed if tech cards could be made in Hydro Plants, as that means it has the same quality ratio as the rest of the chain.
