You can't fully use raid bots yet. If you don't change any of the settings and leave it on the top 100 parses of the last 2 weeks of course it will still be #1 since it hasn't even been 1 week since fire got nerfed.
You have to look at 1 week, not default 2. All parses not top 100 since it has only been 6 days since the fire nerf.
This is all parses of the past 7 days not top 100. Tomorrow we should be able to use top 100 since every day of the past 7 days will include the fire changes.
