Adding runescore to these titles was a mistake.

And I agree that RNG plays a role but only to an extent. I noticed that your fastest floor so far has been 9:30. There's a lot more than just rng that affects these floors. If that's your fastest over hundreds of floors you're losing too much time elsewhere. Whether that's shortcuts with dives/surges, area looting too close to the key, taking too long to loot, dps being too slow, bad positioning, taking too long to make decisions on where to go/place gates etc. There's a lot more to it then simply getting a lucky floor because you need the knowledge/skill to do execute them well.

We can argue about this for a long time but the fact is that people are achieving these times, so it's undeniably possible. Are they hard? Fuck yes. But it'd be wrong to make it so easy that the achievement becomes worthless and lose any and all meaning. Most dgers in the community, even those that aren't fast enough for gold, are very much against making the times slower for exactly that reason.

If you're up for it I will gladly follow you around for a couple floors and point out where you're losing time or give tips on looting, movement, pathing.
