While the new changes to vessels and coalescing visions are appreciated, these currencies should be removed from the game entirely. As it stands, due to the restrictions on running Horrific Visions, players are being punished for actually engaging with the new content more than is absolutely necessary.
I understand the initial logic for their implementation, preventing players from trying to grind out their full cloak upgrades on day 1 of the expansion, but the time-gated upgrade quest handles that just fine. Additionally, if the rate of corrupted mementos gained is an issue, a presumably simple fix would be to implement a weekly cap on those. Similarly, loot from Horrific Visions is already limited to one piece per item level tier per week, so that shouldn’t be a concern.
Personally, I enjoy running Horrific Visions and challenging myself, and would run more each week even with no rewards. However, knowing that the upcoming weeks will require me to complete 6 and then 9 runs means that I can’t do a Horrific Vision unless it is necessary for my weekly cloak upgrade.
Horrific Visions are the only content I can think of (except maybe Mythic Raiding?) that I can’t continue to engage with after I’ve exhausted my rewards from it for the week. For example, if I enjoy raiding, I can still run raids despite not being able to get any more loot.
All I’m asking is that Horrific Visions be treated in this manner, instead of punishing us for actually liking and wanting to engage with the new content.
