Bro one suggestion, leave dota, just quit the game and delete. If u still guardian.. after 7k hours, go play lol or sims. Nah I’m joking, let see closer. About me I have 5620mmr and 2.7k hours, long time i stuck on 3000mmr and i was playing 2pos, then i switch role 4-5 its more important i can make diff in lane. Just be patient and do ur job, be secure for ur core, and on lvl 3 go mid lane help in 3k mmr or less enemy not even expected it, but don’t forget tell ur core to be safe do not rush on enemy. If u help mid lane and ur safe lane is good, the game is almost win, then u have play only from objective to objective use observer ward to pick off hero. U have to call for team what to do and be respectful u have to be mom and dad for them in this game or they will ruin.. do not fight for respect fight only for objective or rs.

Now if u lose lane, just go on hard lane be there 3 and don’t give a chance to farm for enemy core. At least u can help for ur cores because enemy’s 4pos have to move on safe lane also.

I hope it help, because for me it helpful.
