It's probably too late for this but here it is.
Having different stage runs and having each one cost a different amount of money makes economy, game understanding and illuvial/ores balancing a nightmare.
Now interestingly enough there is no reason to do this. Why even divide runs into tiers? It just doesn't make sense
Picture runs without stages where:
We have much more illuvial and ore diversity which has been a pain to balance (and let's agree it's incredibly numb to see 10 times the same stage 1 illuvial in 1 run)
People don't have to think about which one to go, just portal in.
People don't have to speculate which tier is better to get each type of illuvial/ore.
Seeing a tier 5 illuvial is equally amusing and possible for everyone, anytime
Same as above for rare ores.
Easier economy and fuel balance.
Everyone plays the same game.
What's the downside to this? I hear you guys in the comments. Cheers!
