So I know this event is all said and done but is it coming back at all? Like will it be a monthly or every couple of months or yearly kind of thing? can't really seem to find an answer anywhere, thanks.
No at this moment it won't be coming back, We have so far has 2 events this yearm and neither one were the same event. One in February or March and then this one about a half year later. One earlier had to deal with the Rakghoul plaque and this one had to deal with a scavenger hunt.
Right now its looking, based on hints dropped by BW, the next World Event will be in January.
