I've been taking notice that the flash events have been rather unfair as of late and it is mostly because of the world hoppers seeking to get more loot out of the flash events in the wilderness. I get the idea of wanting more loot and all but this also limits on how others gets loot as the people who hop worlds, and speed run the events to get the maximum amount of loot possible effects others who can not do this speed run or dps as fast as them and in fact makes it near impossible for them to get any loot. For example flash events regarding to hordes of enemies swiftly get taken out which gives no chance for other people what so ever to get loot and the proper amount of kills needed to complete the event. There was several times I had to hop worlds just so I could complete the event because of the speed runners trying to get maximum amount of loot out of the event. The suggestion? If you complete the event once, you can't hop worlds to complete it again or another, make the flash event hordes events time limited over instead of being a limited amount of mobs. That way people will have a more fair chance at loot.

OR... and I like this idea better, is that the event itself take 5 mins for each of the steps. when you do hop however after you filled the bar, you won't get loot, instead the bar goes to 0 again and need too do another set of 70k damage (for the cb ones) so everyone can get the damage cap, so everyone gets their reward. Also make it possible to get multiple "sack of very wild" rewards after done twice the damage, you get 2 sack of very wild rewards, you do 3 times the damage (or the gathering) you get 3 sacks etc or make it contain more rewards the more damage you've done. For example 70k damage will get you 2 rewards (as usual) 140k will get you 3 rewards, 210k will reward you 4 etc so make it contain more rewards. But if you hop worlds, you "lose" the progression of the previous world, and need to start again with the 70k damage (which will probably be upped if it's gonna last 5 min).
