I’ve played games competitively over a broad range of genres. I understand voice chat can be a boon, however it just as frequently is a distraction - especially with a pug.
It’s generally a wash. I’ve seen OPs opinion expressed in many forms directed at voice chat, certain loadouts, need for mods, etc. It’s misdirected blame.
Suggesting that the problem is following him game to game simply highlights that he himself is the common factor. Self improvement will always provide better results.
