How you up mmr?

What kind of scripts do you use to up mmr ? I have 6000 hours of dota, using scripts and calibrated season mmr on twink for 2700mmr!! =)) Im always goind with positive KDA on any role. A lot of times im going something like 15-3 but still i can't win solo .

I got 5k for 3 accounts by using ensage.
In my opinion, you should pick hero that good in both push and kill like SF, invoker, arc warden, LC, sven etc. .
Problem in low mmr is you forget to push after kill.
with hero i suggest, after 1 team wipe you can just ask teammates to push and gg.

git gud

Lul 6k hours play still 2700 mmr , i got 200 hpurs play and im ancient

I got legit 3k hours in the game, i'm 700 mmr, my problem is, every time i gain 200-300 mmr, i spam riki afk mid. Now that i seen my problem i'm 1200 mmr and growing, in 2 days. Hopefully i don't fuck this up again
