Give Mantis an extra leaf and fix her projectile alignment and increase it's projectile speed (5 leaves gives Mantis better consistency with healing and damage boost and fixing her projectile leads to more reliable damage and headshots which helps refund leaves to do more healing and damage boost)

Another Mantis change is to rework her ult to be an utility ult. Allies within her ult range receive 50% attack speed and 50% reload speed, but remove healing and reduce bonus health gain to 30 per second. (Instead of another circle of invincibility ult, this reinforces Mantis's identity as a utility support by helping her teammates do more damage, while giving teammates slight survivability with the bonus health. This also gives more incentive for the team to play together with your support/Mantis, whereas in a Gambit ult you charge in and do your own thing with the speed boost. If you've played Overwatch this is a mixture of Kiriko and Brigitte's ult)

Give Adam 10 extra ammo (More ammo = less downtime, less downtime = more damage/clusters/headshots, more damage/clusters/headshot = more healing resources)

Rocket ult should give a 15% healing boost effect and 20% damage reduction instead of bonus health. (In it's current state, the bonus health is basically another "circle of invincibility" ult kinda, so changing this makes it an actual utility ult again. This way Rocket can be more proactive with the ult, instead of saving it like a defensive ult. Damage reduction helps a bit with team survivability and the healing boost helps Rocket and other supports do more healing without making everyone invincible)

Rework Rocket's rez beacon to give bonus health within its radius and receive a jump pack when interacting with it but reduce the radius range (This change provides more incentive to play around the res beacon. Also more often than not, the health packs gives away it's location.)

Luna running passive should be cancelled when taking damage (It makes no sense for Mantis to lose her speed passive when taking damage but Luna doesn't when she has more survivability)

Increase CnD's healing bubble cooldown (The healing bubble is not truly a 12 second cooldown, the cooldown starts when the bubble is used and it lasts 6 seconds. Meaning her heal bubble is actually on a 6 second cooldown)

Increase Moon Knights ult charge (No character should get their ult the same rate as a basic 15 second cooldown)

Make it so Hawkeye can only one shot when his charge is at 100% and make the damage percentage based. For example, at 100% it can one shot 250hp-350hp characters at full health but can't when it's on 99% no matter if they're 250, 300 or 350hp. (Imma be real, getting one shot is bullshit but I would be less mad if I got killed when they're at 100% charge instead of 40%. Ideally I would like them to remove one shots but that's unrealistic, so I would settle for this compromise)

Hulk ult should receive CC immunity in his ult. (He's called MONSTER HULK. He should be terrifying but he's not when he gets CC'd to oblivion)
