I'm just going to leave this here in order to hopefully move the conversation forward and avoid half-baked solutions. Here is a formulation I have discussed with a few people:
The focus ought to be on purchased T5 Stage 3s. To the highest extent, these circumvent necessary gameplay and allow sepETH whales to come in at any time and extract an unjustified amount of value from the campaign.
The proposed change:
-Purchased Tier 5 Stage 3s will forfeit the entire line bonus as well as the respective proportion (1/6) of the tier completion bonus.
This accomplishes the following:
-It avoids too heavily penalizing those who have 'swapped for completion', for example, by selling an Adorius and buying a Phosphorus, as they still retain the vast majority of their tier completion bonus and organically captured line bonuses.
-Thoroughly restrains every single potential sepETH whale that may slowly accumulate and fill their collections with a large quantity of purchased S3T5s throughout the campaign, evading the hundreds of hours of gameplay these activities require
-Ensures that authentic players are rewarded (especially those whose sets are 100% captured solo) in accordance with the spirit of the campaign, which is to playtest the game, not to rapidly accumulate testnet ethereum
