Tweaking the global item weight ratio would be desirable. Less reason to do the same trips repetitively, but not so much that people want to turn off portal restrictions or break their one-character-one-world rule.

Would also be cool to be able to flatten the power curve though that one sounds a lot more complicated to pull off well. I don't mind most of the measures that are put in place to discourage wandering too far too early. But what I don't like is how if I leave my current biome, enemies only come in two flavours. They are either pathetically harmless or boorishly long and pointless to -cheese- deal with.

You don't need to make your bosses take 5+ minutes to kill (solo) when you are appropriately geared to communicate that sense of progression. Fromsoft made that fact mainstream years ago but devs are still doing it.
