If you can convince the village to leave Silverlight en masse today, then sure, that could work. I don’t think that’s likely, but we can try????
Coordinate within factions, I mean. Next cycle, both the H and K factions will probably have four members, which — if everyone’s on Silverlight — is essentially a free Shard.
If it’s lategame, then the factions could also be close to outnumber wincons. I think it’s a lot harder to exe converted elims than to exe the faction leaders. Honestly, I just feel like the village alt wincon is so unlikely that we should plan for more realistic scenarios. But in all scenarios, it’s better if the village has more Shards than the elims. I kind of like your “everyone leaves Silverlight” plan, but I don’t know if the village is coordinated enough to pull it off. What might happen instead is half the village leaves, half stays because they want to use Investiture, and most of the elims stay, leaving them with control over the Shards.
