If the skins in these event chests are going to be SB I’d prefer give them a much higher drop rate in the chest, so basically everyone who participates in the event is able to loot one.
I’m thinking how it compares to Anatis & Cleg from the April Fools Chicken Oryx event which are also SB. Not guaranteed loot, but if you are persistant and do a lot during the event you should end up with one, instead of the disappointment of 0 which these chests are giving for the most part.
That could give a better feeling to the event. It is frustrating to clear a dungeon like tomb, while constantly thinking you aren’t going to get any reward.
