I recently heard our dear developers on stream talking about a possibility of engineer class such as tech marine.
This is a great idea for a class to be able to repair vehicles and possibly spawn some support type deployables (cover, offense)

So if Eldar get an engineer class - The Bonesinger, what kind of equipment and abilities should he have?

Here's my 2 obvious ideas.

1. Repair vehicles ofcourse

2. Ability to build a webgate. Only 1 Bonesinger allowed per squad. Bonesinger can only build one webgate, it would simply act as a spawn point instead of wave serpent. The Bonesinger has to build it and his squad would see on the map where it is exactly.

What do you think?
Anything else?

well.. i don't know if it would be possible due to the game balance, but would be great to have the possibility to build a net of webway gates, connected one another (like in Dawn of War)

Summon weapon platforms?

Summon stationary shields?

AoE armour repair speed and recharge delay bonus.

Personally I think Bone Singers should be an elite class that is able to deploy, weapon platforms, web ways, frontal shields, like in DoWII and vehicle repairs and with the big weakness of being completely unarmed, like not even a knife maybe a shuriken pistol if people are generous.

This is because of the classes capabilities if it gets it's deployables in position and how defensive it can be, I think the class being strong but also as offensive as a baby reduces it's potential solo and encourages the need for teamplay.

Also I think webways would be balanced and kinda underpowered anyway since it's a massive glowing platform that can't move and has no weapons compared to something like a Wave Serpent so I wonder how good it would be if implemented.

True, but also potentially deployable anywhere.

Well, this was nicely solved in DoW2, giving webways cloak ability that can be seen only by certain class/es.
This could be translated to Eternal Crusade easily.
In any case, webgate would mainly act as a quick deploy point for a squad and would not be deemed to last a very long time, just like any other vehicle under heavy enemy fire.
And if it gets destroyed, well, Bonesinger can always build another one elsewhere

As additional nerfing, it could be used only by spawning at the starting points of the map (the ones that have webway gates already) then going through one of said webway gates at which point it pops up the spawn map with the deep-strike webway gate available. Would mean it would take a little longer to use.
