solution for smurfing and wintrading

just change dota 2 to not a free game like 10 dollars or tied to dota +

this will definitely decrease buying account and smurfing problems.

other moba that full of smurfing and cheating and wintrading are free to play as well

what's your opinion ?

————————————-
i have a better idea

add dota+ matchmaking

so there will be two matchmaking system

one is for non dota+
another is dota+ only
