Performance-based roll system

But if everyone is playing it multiple times to get better roll chances, then you're likely to encounter other players who have also run it multiple times and have also got the roll bonus, which results in you not actually having any advantage against them.

If you haven't run it multiple times this week already, and you're paired with people who have, which would be likely, then you'll have less chance to roll, and depending on how great a bonus it is or how much it stacks, you could be guaranteed to not be successful on your first or first few runs.
You will need to run it multiple times to 'build up' your roll bonus, before you even have a shot at winning your loot, before taking into account that you need that loot to drop in the first place.

Basically you will need to grind it out, in order to get back to square one. So this will only enforce more grinding.

I do suppose it would very much leave people who don't start doing the raids on tuesday at a disadvantage, it is pretty much impossible to create a perfect system for the loot, the RNG will leave people running the raids way more than they should but other non-RNG systems either wouldn't work with the duty finder or could backfire.

The only viable solution I can see, is that if the party consists of enough people who have run it multiple times, then the raid actually drops more loot.

More loot would also very much help with getting weekly runs on the raids, at least the 8 man ones.
