Glyph + Black Heart are a superior option in any situation over Rotting Thumb + either of those.
Try to get into ToC 25 regular and get the Stamina trinket off Faction Champions and Get the Skeleton Key when you have the means to do so. Likely you will see a larger upgrade in the Belt vs. the trinket, due to the amount of armor and 3 gem slots in which you can place all +30 stamina gems.
I bought the trinket last after buying all the badge armor items.
There is something so appealing about backhanding someone across the face with a shield.
