Sorry the screenshot is a bit fuzzy, but it seems to me that with the helm of flaming mind being an RP epic and the Wazargs Helmet being better than the Tsukiyaomo helmet, the game is really lacking an epic helmet that is worth getting between levels 250-1200.
The UFSG shows the base stamina of the epics as followed (using levels rather than names)
250 - 100 stamina
550 - 75 stamina
900 - 150 stamina
1200 - 170 stamina
What I propose is simply raising the base stamina of the Tsukiyaomo helmet to a happy median of 125 stamina to encourage the gradual upgrading of epics and to create a better flow in the game itself and its market
