In my opinion 10minutes is just fine, what you are describing is that you do not get enough items, while others do.
The solution to this problem is NOT being able to ff early.
This would just be fighting the symptoms.
The solution to this problem is to make the amount of item drops fairer.
Right now it can be considered unfair, I made a poll in the german forums.
As of now 70% of players perceive the item system as it is now is rather negative.
With the next patch the item amount is being made fairer, but not fair.
It's a step in the right direction, but it's still heavily luck based and the only reason it's fairer than the system as of now is because the system right now is absurdly unfair.
The system that is planned is still absurdly unfair and will therefor not solve your problem.
