Tried to make Reaper fit his role in OW as a high-damage tank buster, while dumping in some talents that fit his lore. His trait is supposed to make him hit like a truck at close range, but like a wet noodle from a distance. Health pool is between melee and ranged assassins. Most means of survivability require talenting.
Making lifesteal his trait felt boring and too Illidan-ish, so I made it a talentable option and focused hit kit around shotguns' properties.
Q - HELLFIRE BLAST
Range 6, Splash radius 2.5
I needed to make Reaper an extra ability since his OW kit leaves one slot empty on HotS ability bar. I don't want to give him much cc, and he already has lot of mobility and survivability in his kit.
W - Wraith Form
Reapers 'LShift' ability from OW. I felt that making him Invulnerable, or even Unstoppable, from the start would be too strong so I decided on leaving it as Protected. Cooldown and mana cost are fairly long to make up for the usefulness of the ability.
E - Shadow Step
Reaper's 'E' from OW. Range is about the same as Ragnaros in Molten Core. Combined with the cooldown it less suited for use in combat and better for covering long distances and getting into unexpected places.
R1 - Death Blossom
Radius 6. Deals damage every 0.5 seconds.
Reaper's ultimate ability from OW. Thanks to his trait it works exactly the same here.
R2 - Tip the Balance
Momentarily enhances Reaper's survivability. Decaying health goes through armor and Shields. I got the idea from Reaper's lore of his cells regenerating and decaying at an accelerated rate.
Alternative R2 - Blackmist Enhancement
Activate to cause Reaper's next 8 Basic Attacks against enemy Heroes infuse them with his cells dealing damage equal to 4% of their maximum Health over 4 seconds, stacking up to 4 times. Each enemy affected heals Reaper for 4% of his maximum Health per second.
A bit of everything, the idea behind Q talent is to make triggering double hits easier, but with the cost of some damage.
