Listen up Netease 
the MMR has gotten way to aggrivating, and it's been getting to us who want to play it casually, and we love practice vs Ai, but now i think it's time you add one thing to Practice ai

Hero proficiency
it's been unfair that you added for all of the modes except for practice vs ai, and we have many reasons why you should add it 

1. Practice vs AI is literally a practice environment.
Players use it to learn heroes, abilities, movement, combos, and team roles without the pressure of a PvP match. One recent discussion specifically described AI as a relaxing place to play and learn without the stress of real matches.

2. Time spent practicing should still count
Let's say i spent 100 hours practicing Wolverine against AI, I'm still spending 100 hours playing Wolverine. Proficiency is supposed to represent experience with a hero, so the time shouldn't become completely invisible just because the opponent was AI.

3. More player counts
if you add this to the mode, you might get more player counts than before, which means more revenue

4.YOU ALREADY ADDED PROGRESSION
you literally added progression in your game in practice vs ai mode, why not add hero proficiency as well into the mode

5. prevent some backlash 
This could prevent some minor blacklashes of characters that needs buffs or nerfs

6. Other modes already demonstrate that AI doesn't automatically mean “no progression.”
This is probably one of your strongest practical arguments. Community players have pointed out that 18v18 with AI can award Proficiency, while standard 6v6 Practice vs AI doesn't. so why not add it to the standard 6v6 practice as well

7. There is a way to prevent proficiency abuse
maybe a Normal Proficiency but with anti-AFK detection or Reduced Proficiency compared with PvP

8.  Players shouldn't have to choose between relaxing and progressing.
Some players genuinely prefer AI matches. One recent player said they primarily play Practice vs AI because PvP makes them nervous, while still wanting Proficiency or stats to count.

So Netease, We marvel rivals players ask you this. to please add hero proficiency onto the 6v6 practice vs ai.
