Fuze's Ultimate is weak, slow and awkward to aim

Been loving Fuze since start of season 8 and i've played a lot him, My only real major problem with him  has been the ultimate, i am Curious to see how others feel on this?

Starting with The awkward aim: It shouldn't aim by clicking on the ground where we want,  it should be the higher we aim the further it shoots (like how a grenade launcher works in literally every other game), because it defeats the purpose of the grenades arc if we can't use the arc to bend over walls or hills to hit areas we can't actually see. And E.g  if a team is on the roof and im on the ground (or even just slightly below them) i can't trap them up there because i can't see the floor of the roof and at best i can make 1/2 a circle of fire on the roof but very likely not to trap anyone at all,

Also find myself hitting Trees or Rocks even though the Projector says it Won't hit anything,

It's also Super slow: to actually deploy the fire, you can hear the whistle of it before it explodes, then from the point of exploding until it hits the ground then even when fire is On the ground you have roughly 5s to Move 10m and totally avoid it.

The process off the whole ultimate takes too long for how noisy and visible it is, I've hardly ever been caught in a fuze ult and any player better then a bot always just casually walks out of it

Easily jumped or avoided: if you have even a slight hill The ultimate is made near useless, as just a 1m height difference between where the person is standing and the ground where the fire is allows you to just Jump over the fire. or if  there's wall in part of you're flame circle you can just Climb the wall and jump over the fire on the ground,

Just raise the height of the flame like 3x what it is and It will actually be able to trap people, The damage isn't high because its more meant for trapping people in one are then Grenade spamming, but if it doesn't trap or do damage it's just useless
