I don't see how difficult research is a natural tart restriction, it simply delays it, as it does all mid to late game strategies

The idea behind the nerfs to gem producers is to bring out different end-game strategies. Early and mid game are always interesting but the end game often devolves into who has the most clams or best tart factories -> GoH and race for Chalice and often Well of Misery. The optimal choices are narrow and the micromanagement with the clams in particular is very tedious

Playing in Bloodless without the gem producers or tarts is really interesting and makes you reevaluate your plans for the end game, if you reach it.
