I just want to contribute this SUGGESTION of mine about making the Steam Community - DOTA2 player names to be CONSTANT not a VARYING one.

FAVORABLE OUTCOME

This is to help the end user (Dota 2 Players) to familiarize his or her friend's name by thier own name codes, since in Dota2 it is a mainstream to use codenames. Changing this time after time creates confusion to the players.
Implementing this suggestion can give satisfaction and less hassle to all end users or Dota 2 players.
