Currently, there is a 0% chance to get any mythic from event chests. One thing I have been noticing with mythics is that people with lower amount of resources who want older mythics struggle greatly to find them. While they are supposed to be hard to obtain, there is currently no way in the game to target older mythics.
I feel like event chests should be changed to offer a drop rate for mythics at a rate in between that of gem chests and VIP chests (more towards gem chests). To allow for targeting, it would be great if event chests would also only ever drop 1 specific mythic per event week. This would allow for the first method to target mythics for anyone who wasn’t able to obtain one during an exclusive week. With 3 and soon to be 4 mythics in the game, it is just going to become increasingly more difficult to get a specific 1 that a player may want.
This would also expand the value of event chests to be worth the extra 5 gems each compared to a gem key as well as the $50 legend packs, the Spoilers of War, and the 60 defend win free key.
