Try reading my scenario more carefully.
The person who wants the information hidden is the one whose performance required less of an initial purchase. That’s not an “underachiever”. That’s a “star”. That “star” does not want to feel pressure to arbitrarily purchase more to make others feel better. If your guild lacks stars, I feel bad for you.
Also, the GW analogy is poor. There are two important differentiating factors.
First, GW sentinel purchases affect higher guildmates directly by increasing the stat boosts of higher guildmates. Failure to contribute to sentinels makes higher guildmates less potent. In the P2W Event (Raid/Invasion/Bounty, they’re the same event…) the only measure is damage/kills. Tier purchases only give more attempts, thus having only an indirect effect on your guildmates. Very different.
Second, GW scoring is vastly different than the P2W Event. GW success is relative to the performance of other guilds, but P2W Event success is to reach a fixed total. In GW, every point counts, every last little bit contributes. In the P2W, every battle has a maximum possible outcome, and the event is finished (for the guild) once the final portal is closed. Purchasing sentinels increases your score in each battle; purchasing tiers increases the number of battles. The information requirements for these very different events are very different.
