For me the idea of the firebrand is amazing, but we dont have movimentation skills to make combos and save us in bad situations, so my suggestion is to add teleportation in each tome skill 3.
F1
Chapter 3: Heated Rebuke: Teleport to target area + Call forth a heated vortex to collapse your enemies together.
F2
Chapter 3: Azure Sun: Teleport to target area + Inspired by countless poems describing the comforting powers of the water-reflected sun, grant boons to allies.
F3
Chapter 3: Valiant Bulwark: Teleport to target area + Manifest the shimmering purity of the desert sun, reflecting enemy missiles.
Axe 2: Change the animation to something more like attack 2 of the hammer and the symbol must provide some boom.
Revise the CD and cast time of all skills, for me is to excessive.
Sorry for my bad English.
