All the bumps were worth. Thanks for answering as I felt like this was a very important topic to make world quests more attractive again for a lot of people.
Giving the ticket itself more possible ways of purpose seems like a very good idea as it would fix the problem of having all legendaries. Also the people who feel like the risk to get a bad non-legendary pokemon is too high compared to the time they invested can just use the ticket differently.
Now I cant talk for everyone but already all of those quick ideas seem lucrative enough to make me do world quests again. Especially the guild island thing sounds very neat as you could do the world quest like a "guild project" to gain access to guild island. Would be a lot of fun for sure.
Maybe people will come up with even more suggestions towards world quests, looking forward to the changes.
