Okay, so I have this: 
[hider=Buster's Abilities]
Combat Role: Support
Sub-class: Defensive Tank
Health: 350 (250 Shields) (100 Health)
Having been a member of the military, Buster has access to similar particle technology with that of Zarya. Said technology was created as a means of maintaining durability for oneself and for allies. Buster has maximized this technology to serve as the most durable healer we’ve seen thus far. 
	Ability 1: Syphon - Buster’s particle shielding absorbs incoming damage and redistribute said damage into a burst heal for nearby allies, and himself. 
	Ability 2:  Health Pylon- Buster plants a small pylon into the ground. Said pylon does 14 points of AoE healing per second to nearby allies. The Pylon has 125 health points (100 health and 25 armor). 
	Ability 3: Alternate Shot- Unlike other characters, Buster must actually switch to his alternate means of fire. This takes 1 second to do. (You would use the primary and alternate trigger buttons to switch back and forth). 
	Primary Fire: Blitz Canon: A particle arm-canon that shoots medium-sized particle spheres out at enemies. The projectile speed is a bit slower than D.Va’s pistol, but Buster can shoot multiple rounds per second allowing for multiple incoming projectiles to deter encroachment. 
                  Type: Linear projectile
	     Damage: 20 per projectile 
			1 projectile shot
	     Projectile speed: 30 meters per second 
	     Rate of Fire: 5.3 rounds per second
	     Ammo: 30 rounds
	     Reload Speed: 1.5 seconds 
	Secondary Fire: Blitz Spread: The obtuse barrel of the canon switches to the side, allowing Buster to shoot four (albeit slower and weaker) particle rounds in a fan-like spread.  The weaker concentration of energy allows for this spread to pass through constructs such as Reinhardt’s shield. It is still absorbed by an enemy Zarya’s particle shields. 
	    Type: Linear projectile
	    Damage: 13 per projectile 
	                       4 projectiles
	    Projectile Speed: 12 meters per second
                 Ammo Usage: 4 rounds per shot

	Passive: Particle Restoration- Much of Buster's health pool consists of shields, and thus can replenish over time. 

Strengths: An incredibly durable healer. While healers like Ana, Mercy, and Zenyatta rely on maintaining distance, Buster serves best as a healer on the front lines. High health pool, and a spike healing capability. With that being said, an Ana could benefit from a well-placed Health Pylon- as she could remain relatively close to the combat and have a means of sustaining herself. 

Buster would work well with a tank hero. Buster is an off-tank support hero that relies on being in the thick of combat. We excels with proper barrier placement from Zarya, some protection from Reinhardt ‘s or D.Va’s shields, or added fire power from Roadhog. Unlike other healers, he isn’t as easily bullied around by Winston. His ‘Syphon’ ability can help his allies make quick work of enemy flankers, but he is susceptible to a flanker when alone. 

Weaknesses: Like most Tank characters, Buster is countered big time by Reaper (or characters like him). While his ‘Syphon’ ability can certainly help against a flanking Reaper, the character’s damage output is just too powerful to overcome without help from allies. Buster would be an obvious target for snipers in that he has a larger hit-box and is a support. However, Buster's health pylons are an even more obvious target for enemy snipers and flankers. 

Unlike Zarya's particle beam, Buster has a particle projectile and thus it can be deflected by an enemy Genji. He also requires another tank to support the team on most occasions.

I wanted to create a character that can work as a healer who doesn't need to have another healer, but can definitely benefit from it. As well, I wanted this hero to be a sort of hybrid of tank and support, but was still obviously served as a support as their primary function. I tried to create a balance between the durability of a tank and the fragility of a healer.  

With that being said I am having a lot of trouble coming up with an ult that matches this balance and represents the character's abilities. If anyone could provide some feedback or some help regarding the ult, it'd be greatly appreciated :)
