Feedback on Corrupted / Scourged Maps

I do like the overall mechanic, it feels quite rewarding and has a nice risk / reward balance.

One downside though:
If you clear the Scoured / Nightmare version of your map faster, than you clear the regular one, you will keep getting teleported into an empty Scourge Realm, just to teleport back into the regular map with an almost full Blood Crucible, causing you to shift between realms constantly.

That may only apply to scourged maps, which forcefully teleport you into the Scourged Realm, once your Blood Crucible is full and will only drain your blood, if you kill scourge enemies.

I am not sure, if all scourged maps work like that (only did one map so far and had this happen).

Maybe give us the option to completely empty our Blood Crucible, if there's no point in going over to the Scoured Realm, because it has been cleared already.
