Hey my name is Rustam and i love playing videogames such as dota 2. Playing dota since 2012, all time i was playing support or offlane role, my mmr peak was 7000 ~(top 800-900). Had coaching experience in russian website - anylvl.com.
My favorite role - pos 4 support and most successful heroes is. Rubick, Tiny, Batrider, Io, Earthshaker, Grymstroke.(played many games in a new heroes: snapfire - ~100 games with 80wr, and pos 3 void spirit with 80 games and 70 winrate).
But at the beggining of my dota experience i was playing pos 5 support, so i know about all tips and tricks at this role.
I played not only with a pro players in public games, i played many games in a low mmr bracket, so i know all common mistakes from this mmr bracket, In my honest opinion, i think the most hard mmr bracket is - 4k, because players at this bracket playing better than newbies, but they have so much ego, so its to hard to communicate with them.
Coaching Methods, I provide:
I highly encourage reviewing games alone, as finding and fixing a mistake on the spot is beneficial. If the same mistake happens repetitively and you have no idea how to fix it, then I would recommend getting a coach.
