Return Mangler and Blessed Penetrator

Upgrading anything will always have better stats. As it was said, upgrades were made only for those who want to upgrade their favorite items, therefor it'll be very expensive as item itself is good already.

Regarding twigs and rupturers that you mentioned, I think the +1 dmg change was made cause everyone was talking about how ruptures are still better cause of +1 more dmg, (just my guess).
Upgraded twigs were supposed to be better, and don't forget, adding more damage to spears automatically decreases some of the accuracy, so to some players that might even count as a nerf.
