Doomfist and his issues

Hi everyone this is Vlado , writing this post from home.

As I like to play from time to time Doomfist /not competitive/, I have seen some frustrating moments about his controls, seizmic slam, rocket punch. Some combos can be landed only by luck and doomfist without mercy or other useful support is instantly dead, doing only sometimes more then 2 kills. How is this DPS, when all you do is kill one squishy and landed death?
This hero was way more fun before and even if i dont pick him for competetive, he needs perman. armor or some escape tool, or cool. reduction for rocket punch.
Now its hit or miss. This is not fun and its not rewarding anytime.
Even his Meteor strike is mostly 1 kill - or escape.
Most of the time his only defense is 4 shots and he is dead.
Blizzard should give Doomfist 250hp/50armor permanently or fix cooldowns.
What are your opinions?
And don´t say that pro players play Doomfist. Not everyone is so good like some pro players. Most of the people have also personal life and interest and don´t need second job to learn to play Doomfist properly.
