Being silver for a long time really handicaped my willingness to group
It got to the point of seeing the word "group" would make me cringe. Just so many flashbacks of 50 min games where everyone starts grouping at 20 mins and plays ARAM until eventually death timers too long that one team can end.
The solution I came to this year was basically look to see if "group" means "play patty cake with enemy for 5 mins", which normally that is what it means so I would just afk farm a lane and push to get more items before a late game fight.
But now when people say group I realize they are starting actually mean it because "shits about to go down". I am slow to react sometimes since I am still in the mindset of "have to farm as much as possible can't trust my teammates for shit". But now I can start trusting my teammates a little more and have to be quicker to react to what is going on around the map.
Tl,Dr May have to adjust your game play strategies depending on what elo you in. You don't have to play like a diamond player to get out of bronze/silver or w/e elo you may be in.
