The speed differences between Mace builds and other builds is the biggest problem

Deadeye gets tons of move speed and atk speed from the tree and ascendancy, while Warriors are the complete opposite, having move speed penalties on armour and atk speed penalties on the tree/gems.

You are objectively at a disadvantage the moment you equip a mace, compared to other weapons like bows or staves or casters. Maybe the slower speed could be compensated by having more AoE, more damage or more defense? But it doesn't.

And this is a BIG DEAL because the most important thing in this game is clear speed, mapping is what you do most of the time and if you're fast you make more money and buy better gear and get stronger faster.
