Hello,
I have run VMA over 100 times now and I've heard other people run it 200 times and still not get what they want. Now I understand this is an end game content dungeon, but over 100 times and still not see a Sharpened Inferno staff drop? That's pretty terrible, I'm to the point of quitting the game altogether because I'm so sick of running the same content over and over again.
Here's a few suggestions:
1) Remove the traits Decisive, Powered, Defending and Charged from your Inferno staff selections and also either remove or significantly reduce the drop rate of your sword and board. Here's why, end game content will never, ever, EVER require you to run those traits and no tank or build will ever call for a VMA Sword and board, they are useless and therefore should never drop.
2) This is my biggest suggestion. I think this would help people that are sick of grinding this place get what they want. Implement a token system, in which, after every completion you get a single token. These tokens after collecting 100 of them can then be traded to the vendor in the beginning of VMA for a Sharpened weapon (or whatever trait you want) of your choice. You can also include a random drop at the end of VMA as you already do.
This would allow 2 things to happen, one you could get lucky and still get you a Sharpened weapon before your 100th run and two if you're unlucky like me, you could be guaranteed a Sharpened weapon of your choice at your 100th run.
I think this will help motivate the people that are quitting VMA (which are all my friends) because they can't get their Sharpened Inferno staves run VMA more without actually giving them the staves for free (it still takes skill and dedication to run it a 100 times).
Please read and consider implementing, I'm getting sick of running VMA and would really like to dedicate my time in ESO to something else...
