Orisa by SnowChaser

First things first, I take no credit for any artwork I have used, most of it is official blizzard stuff and some of it is fanart. This concept was heavily inspired by Orisa (duh) and a distinct lack of counterplay to targeted projectiles in HotS.

Level 1

Penta-Tank - Increase Orisa's out-of-combat movement speed by 10%, but reduce her in-combat movement speed by 5%.

Protection Satisfaction - Quest: Absorb 10000 damage from Heroic sources with Protective barrier
Reward: Reduce Protective Barrier's cooldown by 2 seconds and increase it's size width by 20%.

Not So Fast - Quest: Kill enemy Heroes within 3 seconds of them being pulled by Halt.
Reward: After killing 5 enemy Heroes, reduce Halt's cooldown by 1 Second and it's mana cost by 25.
After Killing 10 enemy Heroes, Halt's slow is increased by 10% and lasts 1 additional second.

Level 4

Defensive Mobility - Fortify increases Orisa's movement speed by 20% for it's duration.

Robotic Throwing Arm - Active: Throw a Protective Barrier with double range, but 30% less health. Shares its cooldown with Protective Barrier.

Stream-Crossing - Orisa's Basic Attacks do 30% more damage if they have passed though a Protective Barrier.

Level 7

Fusion Cannon-Exertion - Activate Orisa's trait to remove its movement penalty for 6 seconds.

Fusion Cannon-Extension - Activate Orisa's trait to increase her Basic Attack range by 1.5, but prevent no longer be able to move while attacking for 6 seconds, or until re-activated.

Fusion Cannon-Reduction - Activate Orisa's trait to reduce her Basic Attack range by 1, but increase it's damage and her movement speed by 40% for 6 seconds, or until deactivated. (still is movement impaired when shooting).

Level 10

(see above).

Level 13

Collateral - Halt does 150(+4% per level) damage to enemies it passes through.

Pyocyanin - Basic Attacking an Enemy for 1 second reduces it's movement by 10% for 3 seconds, stacking up to 3 times.

Motivation - Enemy Heroes 'Halted' during fortify increase it's duration by 0.75 seconds.

Level 16

Rough Landing - Halt deals 130(+4% per level) to all enemies at it's detonation area

Overheat - Deal 20(+4% per level) damage to nearby enemies, increased by 50% during Fortify.

For your own safety - Enemy Heroes that touch Protective Barrier take 85(+4% per level) damage as long as they remain in contact with it

Level 20

Time Flies - Primary Concern's cooldown recharges 10 times as fast while being channelled

Supercharged Supercharger - Supercharger increased allies damage output by a further 10% and lasts until destryoed

Nomadic Fortifications - Active: Teleport and Fortify all nearby Ally Heroes (70 second cooldown)

Repulsive Barrier - Enemy Heroes that touch Protective Barrier are knocked away from it.

The vast majority of this concept was designed late at night and the numbers were theory crafted very, very loosely, so it's more than likely that Orisa is grossly overpowered, So she'll fit right into the recent cast of HotS (I'm kidding, leave me alone) but if anyone has too much time on their hands or has theory crafted a similar design before would like to get in touch, I am more than open to hearing what you have to say, as i am about any other constructive feedback or just generic praise <3. I would like to thank you for reading through my wall of text, and Would greatly appreciate anything anyone has to say about it, THANKS!
