Stadium Need: Nerf, Fix, Fix Challenges

Challenges:
1: Reduce the requirements for wins and games in Stadium mode.
Play 15 matches win is counted as x2, Need 8-15 games match lasts on average 25-40m(Excluding matches 3-4 wins vs 0-1 losses. 11-16m).
8matches x 30minutes=240minutes=4hour
15matches x 30minutes=450minutes=7,5hour(7h30m)
Game in Stadium should count as 4 games(If win 6-8 games) since the average duration is 30 minutes(5 times longer than a normal match).
Game in Competitive should count as 2 games(If win 3 games) since the average duration is 8-15 minutes(2 times longer than a normal match).
Normal match duration 4-10m.
2: Win 3 match use Tank/DPS/Heal. Due to imbalance of certain characters and small hero pool, it is impossible to complete part of the challenge.

Who hero need Nerf:
Undying Zarya

Soldier-76 - Aimbot after Shot with grenade launcher. if you make grenade launcher aimbot it kills almost anyone DMG/Heal for 0.5-1s

Reaper - One shot DMG +400hp
Whoever made items for Reaper didn’t know how his damage works.
Damage 5,4 per pellet, 20 pellets, 5,4x20=108 per shot, and X2 DMG for Headshot, Iems +25% Pellets=20+25%=25Pellets with item, Item +50% DMG for attack spine/behild.
5,4x2(Headhot)+50%(Item)x25(Pellets with 25% buff item)=405DMG
This does not include other items/powers for DMG.
I would add power that adds shooting from grenade launcher(RMC=RightMouseClick) like from the first trailer.

Remove useless Item/Powers:
Ammo clips(increase ammo in clip) - For Reinhardt, Diva, Orisa and Moira they don’t have them.
Ability power - In some cases, heroes’ abilities don’t deal damage/heal and it doesn’t do anything. Example: Reaper.

Conduct survey about useless/weak items/powers and remove/replace them.
And also too strong items/powers to nerf/remove/replace.

Some of the items would be better implemented as purchasing characteristics like in TF2 Mann vs. Machine(TF2 MvM) and significantly reducing the number of items.
1: Reducing the number of selectable item to 3-4(Instead 6) but they will be more powerful and significant.
2: Remove items that only give stats. Instead of these pecks make purchase of characteristics like MvM Uprade.
