New Class: Chaplain

I second that. We need a Chaplain like from the warhammer 40k space hulk game.

These support abilities would do well in the service of the Emperor. The "stockpile effect" for support classes would be an amazing implementation as well. 

Honestly, I think a mix of 2 and 3 would work well for a class ability. The Chaplain could recite a litany that lasts about half as long as a Bulwark's banner with the tradeoff of being mobile, and it could have different effects, depending on which Crozius you have equipped.

Like one Crozius making their litanies provide a damage buff, and another doing something like increasing parry windows, or filling teammates recoverable/white health so they can execute enemies and heal, etc. The whole duration of which you can hear the Chaplain going full Angry Preacher mode.

I imagine the squad banter between a Chaplain and some of the more zealous characters/classes would also be hilarious.

Isn´t the melee support character the role of the bulwark? However as chaplains armour is sick I don´t compain

For the chaos side you could use a dark apostole model, with word bearers skin. 
Also since the Dark Angels are coming, they need special chaplain skins. 

I would love a Chaplain class. I don't know exactly how much the limitations of the role would prevent it from being added but I'd certainly love it!

From your abilities I think I also agree that number 2 would do well since Bulwark already provides a defensive kind of aura, but I'd like some changing mixed there as well or the character saying some words after activating the ability. 

I also think the Crozius look cool, I just wonder how long it would take to add Chaplain just for the fact they'd have to animation all the finishers for the Crozius. And I wonder if Chaplains are allowed to use anything else or if lore wise that would lock them with Crozious. I'd like to see a a two handed Executioner Blade that I've seen some WH40K miniatures wield. 

Personally I like the idea of what I'd the Chaplain buffs team perks. 

Class passive could be a team perk like 5% to damage, damage reduction, ability recharge. 

Class active: doubles the effect of all team perks for 10 seconds. 

Then the last column could have active modifiers like reduces length of active but 4x the team perks. If the ability is active a majoris execution adds 5 seconds to it. And finally the heal, each team member heals 1 stim worth of health.

Link it to the mic... if you chant the litany of hate together then an aura should form 🤣

(Unrealistic but cool AF if you have a hard-core RP chaplain on yoir team)

We for sure need a Chaplain that either gives us a DPS buff or gives us extra armor or damage resistance. I would also like to see a proper Healing Support with a Apothecary and maybe a technical support using a Techmarine maybe even area denial ability that uses a Tarantula Auto Turret. 

Definitely agree having a chaplain would be cool
