Only way to judge an IGL is to listen to team comms which we cant do.
As a result theres no real way to judge IGLs so hltv makes up random shit.
Usually focused on how many events the team is winning.
Put 2018-19 gla1ve on a team without device, dupreeh, magisk & xyp9x and HLTV would say hes the worst igl in history. Even though he could reinvent the game.
Comparing IGLs is near-impossible without just taking player opinions. But to be honest comparing players at all has always been stupid in every sport
