Unfortunately I have to agree with the majority of the feedback here, The quest chains doesn't favour the casual player, working 6 days a week I don't get to play a lot, and with that said I doubt the hardcore player would stand a chance completing this without spending a lot of real money to meet the deadline.
The rewards seem balanced and fair.
But the timer should be removed or set to perhaps 3-4 months.
Overall its a great idea and well welcomed, just needs a small adjustment
