@CAGOA34just to officially state my opinion here (in the topic probably tributed to me):
20 bomb aka 20 kills in a game badge - what does it represent?!
If your k/d is close to 20, then it shows how good you are.
If your k/d is close to 10, then it shows that you are good and probably have a good team to respawn you regularly (or something like that)
If your k/d is 5, probably one of those odd lucky moments
If your k/d is sub 5, well then it is close to once in a lifetime moment for you, enjoy, it will never happen again
Theories and numbers aside - do 20 kills in your max rank lobby, I will shake your hand, so far never seen it happen even when Predators enter Diamond lobbies, a hacker once did 17 kills with aimbot in Diamond lobby, 20...haven't seen.
Any other 20 kill game is generated via hacks and/or huge skill gap between you and your team (who definitely gives you the kills, otherwise you would probably finish on 6-10 each instead 20 for you only).
In most cases, unless it is hacks + nofill game, 20 kill badge shows to me that you as a player probably begged a team to leave kills for you as soon as you hit like 13/15 - sad case, shows how low people can go just to get a badge.
Potentially you farmed kills, some find this an easier way to get the badge vs begging or hacking.
Anything else... no, not really.
When I see this badge, 4k badge, Master's badge in the game in my team I just know that at least one thing will happen:
1. player will be arrogant as crazy expecting other team members to play "as good as him/her" seemingly ignoring the fact that they don't have those badges
2. player will act like rambo, push every fight, die or set the team up for failure in winning the game just to gain his stats - google Russel Westbrook in NBA, read about him, you will get what I mean
3. player will think him/her first and use the teammates as cannonball meat / lifeline (preferably you play one or Giby, so you can pick them up every time he gets knocked) as a favor they will take all the glory so you don't need to carry that burden
20 bomb badge in nutshell - you got lucky, killed at least 10 people who had no clue how to play this game well, begged the team to give you kills or used them as decoys, you probably have messed up values and play this game as a single-player rather than BR/team game, that in my eyes make you as low person in real life as I am as a player for you in the game.
Badges that I am proud of - squad did survive / did not get knocked / respawn 2 or more times in the game and any other that shows your IQ, teamwork, ability to play with 2 people and communicate clearly.
p.s I have removed all badged and stats from all my legends and will never get those back even if I get 4k and 20 bomb.
