His passive would allow him to repair and temporarily take control of enemy ramparts and turrets respectively by meleeing them. Repair % is doubled with hammers. This consumes a small amount of energy per hit.
His first ability should be mine layer/a tool box styled skill
Combine his 1st and 4th abilities into 1 unstable violent orb or "mine" vortex, both shocking and magnetizing enemies near it while pulling in any that get too close. only 1 can be up at any given time, the idea behind this is to give a turret that has some independent nature to it but would also be effective in keeping a very small area crowd controlled.
Combine the concuss and shred mines into 1 proximity mine, that deals blast damage, shreds armor by 40% and shields by 60% while also placing a rad proc on all enemies in the radius. These can be tossed directly into the vortex to immediately detonate and effect those caught in it. These could also seek out enemies much like Seeker units Latcher mine/grenades.
Keep bounce mine, now while this may seem silly, I want it to stick around but I want it buffed and the velocity dramatically increased possibly based on duration. I want to bounce across orb vallis on these things or high into the atmosphere. This may seem like its just for fun but any enemy that touches it is no longer your problem and is likely now somewhere in the upper atmosphere. This can be tossed into the vortex to expel those in it. The bounce pad could also be used to bounce projectiles off its surface.
This second skill is based around team support
This support station will randomly produce a health orb, an energy orb or ammo, ammo taking priority over health and health over energy something like 50% ammo/35% health/15% energy production chances, this deployable object has health and can be destroyed which vauban can repair with melee which will consume less energy overall than redeploying it to an extent. This would likely use either vaubans health or shields to scale up the health of the object, this would be an interactable station much like the health station deployed by the mantis landing craft but with far more usability
Third skill will continue to be Bastille but with some minor alterations
These alteration include slowed projectile speeds and reduced damage towards allies inside the bastille cage, the "wall" of the bastille cage could possibly allow for mines to be attached to its "surface" any mines placed would fall directly down if bastille is nullified or its duration runs out
This 4th skill is a deployable rampart much like the grineer rampart emplacements
The rampart would match vauban/vauban prime in the respective "train/locomotive" themes, imagine the front of a train but with guns. This deployed rampart would feature a similar overheat/battery mechanic as grineer ramparts and object class health scaling that the support station has. Rampart deployable would be usable by allies.
Now for this post to disappear into the depth of the forum where neither I nor anyone else will ever see it again. Choo choo!
