Frankly silver tier is so bad that whether or not you speak will make 0 impact on the game, you can play csgo at top tier mm level without voice. At your level you should strictly focus on your own improvement and performance instead of bothering with all that lol.
well so i am unlucky because i mostly know all the maps (not overpass) , i know lots of dust2 / mirage smoke spots and practiced them offline , i surely can aim after i put some hours in aim / dm only hs maps and all i can do in MM matches is trying to make a simple strat (t side) and have the control of the map but then suddenly i ask myself : "why i train smoke grenades inside window on mirage when people try to rush mid but they stop on ramp and die miserably from some stupid ass in the connectors?"
and how can i improve if i find myself alone in B in dust 2 and i need a trigger bot to kill the remaining 5 terrorists?
i don't want to play like rambo but seems silvers tends to do so.
i'm actually thinking that the only way to improve is gather some friends at your level and play toegether.
recently we encountered 2 "smurfs" playing like ninja monkeys , trying to knife , trying to ninja defuse and miserably dieing , they wanted to lose that match , they said their main was a mg2 but seriously who gives a fuck about the ranks , i don't , i just want to play the game in the way is meant to be played.
