With Inquisitor Martyr nearing release in this quarter, here are a few suggestions for the future updates.

A few thoughts pertaining to runes for the other classes along with some armor abilities.

For reference, I relate toggle abilities to be like the assassin's stealth armour skills

Crusader:

- heavy armour

- ‎tank

- ‎cqc

Runes:

- basic damage reduction (DR)

- ‎DR after deflection

- ‎DR after block

- ‎resource on block

- ‎heal over time on do deflection

- ‎stun on deflection

- ‎blind on deflection

- ‎bleed on deflection

Armour skills:

- vortex: suck foes in and stun them, dealing minor damage

- ‎courage/valor: buff self and allies with damage buff and health regeneration

- ‎Emperor's blade: strike out at foes with a fiery blade that emits a penetrating wave of fire.

- ‎automata: summon a mobile turret, dealing less damage than the tarantula but attacking more regularly.

- ‎retinue: summon the imperial guard's finest

- ‎valient charge: charge a single for dealing massive damage, enemies surrounding the target are stunned.

Assassin:

- fast attack

- ‎dodge

- ‎damage over time

Runes:

- base Dodge chance

- ‎DR after Dodge

Armour skills:

- back stab: teleport behind a targeted foe, dealing heavy combined damage of ability and weapon damage

- ‎deadly waltz (toggle): gain evasion, on evasion; deal extra damage on attack.

- ‎mind war: foes actively ignore the assassin with the aoe

- ‎toxic illusion (toggle): gain the shape of the foes you are fighting. Enemies ignore you at a certain distance. Gain access to toxic needles that break on a single strike against a foe dealing heavy damage over time. The illusion breaks on attack.

Psyker:

Armour skills:

Reverberation: sent out a wave that suppresses and breaks armour dealing minor damage.

Tempest (toggle): ranged foes have a chance to miss/ melee foes are slowed.

Thank you for reading,

Keep up the good work devs!

Addendum: 

Due to runes being more of a space wolves thing - perhaps these instead?

Trained skills - crusader

Augments - assassin

Arcane codex - psyker
