Alliance Boss Event

====
The event that started on the 24/04/19 brought some changes to the Alliance Boss system w.r.t Fury Farming. You can read about them at Alliance, but in general they just increased fury spots from 4 tiles to the whole corresponding area group.
====
The alliance gains event points for every alliance boss defeated during the duration of the event, before the update that ends it. The rewards are lucrative, with gems in multiple 100's for everyone, not to mention summing tickets IV (high chance of elites and masters).
The points are calculated based on (1) level of alliance boss killed, and (2) number of participants. As (2) gives about 10-15x the points of (1), to even have a chance at winning at 45-50 members of your alliance should participate. The tie breaker between alliances that had high participation and fast fury farming is the level of boss killed : consistenly killing higher level boss puts you at an advantage. 
Note: Some alliances are very strict about participation, so you may get kicked if you don't participate. Go talk to them and resolve any issues.
