I've completed the event license and crafted pretty much EVERYTHING I could in the event crafting.
525 each for Ash and Dust is kinda tough but daily and weekly objectives made up for it (though I never finished 100% of daily objectives, I did managed to weekly).
So I guess overall the event is achievable if you spend a few hours everyday.
The only problem is the crafting price, which is kinda high. Without all the credit savings for the past months I wouldn't have got much out of it, despite completing many tasks.
I spent pretty much 500m+ on them in total :D
Oh and also, Flop raid is too difficult I guess it's for geared players but don't you think we should make it for everyone?
