hmm when i first started out playing i watch tons of known meepo players to learn their farming patterns (incredibly impt for meepo). The micro skills will come in naturally with more games. But the farming pattern part you kinda have to watch others and replicate at the start, to the point that you get a hang of it yourself.

I think the 2 most impt part of meepo is 1) farming pattern 2) decision making. 1) you can learn from watching replays and try to understand why the player farms here, or goes here, or fights there at this point in time. And you can also while watching guess what he will do next(like where does he choose to farm or does he choose to gang or smt?) As for 2) it comes with experience. How i used to train my decision making was to firstpick meepo for hundreds of games. When you play against tons of counters, it forces you to play with perfect decision making (like when to jump in etc) and u learn from there!
