which 4* characters to evolve?

[thealchemist]

Hi there
After learning on the fly and basically evolving whatever characters I had available at the time, I have since been hoarding 3* evo shards to get the maximum out of them next time I choose to evolve. Currently I only have 3 5* Eddies (original Holy Smokes, Gunner and Grim Reaper) and 1 Assassin Soulless demon, 1 Sentinal Newborn of Light, 1 Assassin Axis Bomber Boy, 1 Magus Corrupt Rescuer and 1 Magus Pharoah Dog King. I have enough shards to evolve 1 Gunner, 1 Warrior, 1 Sentinel, 1 Assassin and 1 Magus character. So which characters should I evolve? Here is the run down of what I have at the moment.

Warrior
Axis Bomber Boy
Corrupt Droid
Soulless Demon
Golden Son
Possessed Rockets
Demon Dog
Harpy

Magus
Masked Harpy
Corrupt Owl Cultist (with 3 skill shards which in hindsight I should have saved)
Axis Soldier
Allied Soldier
Newborn of Light
Wickerman Eddie
Speed of Light Eddie
Possessed Mine

Gunner
Corrupt Droid
Undead Allied Soldier
Possessed Rockets
Desert Golem
Desert Marauder
Gunner Dog

Sentinel
Undead Rescuer
Fear Of The Dark Eddie
Angel of Strife
Allied Soldier
Mummy Eddie
Dog of War

Assassin
Storm Eddie
Undead Rescuer
Undead Axis Gunner
Pyro Soldier
Desert Rider
Axis Soldier

Warrior - I still can't decide 100% between Golden Son, Soulless Demon (for atk and def raise) or Bomber Boy (accuracy passive).

Magus - I like the Harpy because of the passive of immunity to be stunned, frozen, blinded. I'm currently not considering any of the Eddies as I like Grim Reaper Eddie a lot.

Gunner - I am strongly considering the Desert Marauder, but Undead Allied Soldier could be a good party healer to have.

Sentinel - I'm really leaning towards the Undead Rescuer as he has good stats and ability to remove buffs from opponents as well as debuffs from my team on top of being a healer. Has decent magic stat too. Fear of the dark Eddie makes me pause somewhat.

Assassin - I have two 5* assassins at the moment so not a urgent need for another. Its probably between the pyro soldier and Storm Eddie but Undead Axis Gunner or Axis Soldier could be a consideration perhaps? I hated the Axis Soldier in Battlefield.

Anyway I am interested in people's thoughts, hopefully with your pros and cons for each. Thanks in advance
