How a versatility player can gain mmr?

[f*** gaben]

Hey, basically i was a dota 1 pro living in the game since the time i would wake up until the time i would go to sleep for many years, exactly like the todays pros do in dota2.
When dota2 came out it was exactly when i had to get a job and start living the daily routine so i never bothered playing professionally but i would never miss a tournament stream or a patch changelog notes to keep my self updated.
Playing for many years for literally fun i would abandon games instantly or grief not caring about anything since i couldn't knew that i would be end up playing this game a lot so i ended up in a situation where im stuck at 2000-3000 mmr for many years because of my 90-100% versatility score. I noticed that if i keep spamming my good heroes i will be on the road to the immortal bracket BUT i swear to god i cannot play the same hero twice in a row, if not many days have passed im so bored to play the same hero so i keep playing the entire dota pool as i was doing in dota1 but this does not work anymore like in dota1, playing different heroes is super risky and it would never let me raise my MMR...
Im kinda stuck and i don't know what to do, im pretty sure i dont deserve in my rank because i have like over 15 years of experience in the game and my plays usually are insane so what i must do in this case to get to divine-immortal bracket if im not willing to play the same heroes often?
