What do you like or dislike about the latest Vana'Bout event?
The idea of a "competition" to encourage engagement is a great idea. Giving players both personal goals and community goals can encourage players to take part. Earning points by setting RoEs is a good system.
I would love to see a future VanaBout that isn't tied to "you have to log in every day and grind objectives", though.
How do you feel about the objectives and their difficulty?
Given the content required (Ambuscade), the objectives are too strict and actually interfere with regular Ambuscade runs. Keep in mind that most players only do a few Ambuscades every week, so having to do at least 3 very specific runs every day doesn't make a lot of sense. While having varied objectives is an ok idea as it incentivizes having multiple jobs, the reality is that most players focus on one or two specific jobs and may not be able to complete all of the objectives.
The vast majority of points comes from grinding Ambuscade daily - and this just isn't how players these days actually play the game.
What changes, if any, would you like for future iterations of Vana'Bout?
The first major change would be the rewards. The rewards are, quite frankly, awful for the amount of time you need to spend to get them. I actually don't mind the Etheral Weapons for a low-tier reward, but the Silver and Gold tiers really don't incentivize players to get them. The only real standout award is the 100 Deeds, (at Silver) but all three tiers should have had multiple choices of similar value to really make the event worth it. Also, the reward for reaching the community goal is...you get to do more Ambuscade with free Seals next month. It doesn't make a lot of sense.
Tying VanaBout to a daily RoEs also seems like a poor choice. Yes, you want players to log in every day but a large portion of your current playerbase only logs in maybe once or twice a week and that type of player should be able to take part in the event too.
One final note: The initial estimate of global points to achieve was WAY off, I have no idea where the number came from but it really speaks to the fact that SE has difficulty understanding just who and how many players actually play the game at this point. Yes, it is a 21 year old game, but getting active player counts shouldn't be too difficult. Even with the 75% reduced goal the playerbase still might not hit it as the rewards vs the time investment aren't really worth it.
I would like to see other VanaBouts that focus on content that doesn't need to be grinded every day.
