In fact clams were only 2w 10 gems in d2, and so the cost and trouble to get them was hugely increased but still they remained very important part of winning strategies despite that, so I don't think any reasonable cost increase can change that. They should be somehow limited to the actual size of player's lands or gem income from sites to make them comparable with other investment options, unfortunately it can't be done with modding tools we have.
