An Axe/Scythe is not a press 45465486 Warcry button Weapon

The axe is very weak compared to a rare.

The build archetype is also underwhelming.

However, you don't need to press anything for flasks nowadays. I don't believe any build would use six warcries. Some warcries don't exert any attacks like enduring cry. Your curse comes from your weapon automatically.
