The usual timeframe for troops from weekly events is
3-4 weeks (which for the weekly events has actually always just been 4 weeks from the announcement / start of the event, and 3 weeks from the end, almost like clockwork – some things seem to have manual slip ups, recently).
The only troop releases that have “4-5 weeks” listed are Holiday Event Legendaries and Legends Reborn pets – why the recent increase, I can’t say:
However both of these are still in contention and haven’t really been resolved:
Per Fourdottwoone’s post, there have been 4 full weeks between the end of the Vulpacea Kingdom Pass and the start of this week’s event.
Please communicate this very strongly with the planning / programming teams. It sounds like they don’t believe it is important to give you the correct information on release times, or in a timely fashion either. That needs to change.
