Is very annoying when are you saving Common materials for a desired upgrade, and so you have to upgrade a legendary equipment with Uncommon/Rare material just for disassemble it to receive more Common materials for finally get enough Common materials ... The upgrade animation is so annoying to wait... Im wondering if you can just add an option for exchange it directly from Uncommon/Rare/Epic materials into Common materials (100 Uncommon OR 50 Rare or 25 Epic materials for 250 Common materials (the same quantity that you receive doing the upgrade/disassemble)

And maybe, an extra: Allowing us to create these Uncommon/Rare/Epic using Common materials (same way: 250 Common materials for 100 Uncommon OR 50 Rare OR 25 Epic materials)

No bro.. the current rates doing upgrade/disassemble is:

100 Uncommon for 250 Common
50 Rares for 250 Common
25 Epics for 250 Common

It means that it should be about:

2 Uncommon for 5 Common
2 Uncommon for 1 Rare
4 Uncommon for 1 Epic

1 Rare for 5 Common
1 Rare for 2 Uncommon
2 Rares for 1 Epic

1 Epic for 10 Common
1 Epic for 4 Uncommon
1 Epic for 2 Rares
