Pheonix is by far the weakest character in the game he needs reworks not buffs .
I will give my idea for ideal buffs and then the why.
Ability 1: Blaze- Less damage when shooting through it and it can cut above surfaces. When the wall ends it gives a fire affect to players in a 7m radius. This decays them.
Why: This will help his team push into site and help push enemies off of site after the wall goes down, for the damage aspect it would be like a wallbang.
Ability 2: Heater- Extra bullets that become somewhat of a raze rocket but it is just two bullets added to your gun. When you shoot it within a 10m radius of an enemy player it gives the same decay affect as Blaze whilst making them deafened.
Why: This would push enemies off of site and stall them for example your sova darts someone back plat you throw you Blaze and shoot the Heater at him, think of it as a neon stun.
Ability 3: Cruve Ball- Stays mostly the same but can no longer flash teammates and is throwable like his molly
Why: He has flashes make them diverse, throw them over boxes, give him the ability to throw kay0 esque flashes or his normal curve balls.
Sorry for any errors im on vacation so im on my phone.
