I will say my most honest opinion on this phrase:
Let's define this. This two word phrase is used when the user simply thinks his matched online strangers are incompetent, and for others, this phrase is used when the user does well on an online game, but his team doesn't.
To note, I'm not a unicum or so. I'm not even on the standards of "above average/good", but rather on the joe average side of WoT players. I do play well, but I do make some careless mistakes here and then.
But let's see some of the examples that we see very often.
Bob is a great player. Today, he went on a Jackson on a tier 6 match on a city map. He did his best for his team, supporting the flanks, doing ~1k damage, but only seeing his team disintegrate very quickly. Since he's on a Jackson, he doesn't have the potential to carry his team with his bad traverse speed and his bad armor. And so, on the last few minutes of the game, he says "fuck noob team you all suck".
Let's look at the perspective of other players, but on the same match Bob is at.
Dan is an average player. He's on his tier 5 artillery, the M41 (155mm HMC). He's only played around a thousand matches. But since he was on a city map, he couldn't fire at places he wanted to, but even when he got the chance, he missed noting the horrible accuracy of his tank. He was only able to get ~200 damage done, and saw some random teammate saying "fuck noob team you all suck".
Ryan is a bad player. He's on his tier 4 light tank, the M5 Stuart. He's only played ~500 matches. He tries his best to scout and to flank, using his good enough knowledge of the game, but he gets killed in the process. He, on the end of the game, sees the random teammate's message as well.
Kevin is a good player. He's on his tier 6 heavy tank, the KV-2. He's playing this game for absolute fun. He always thinks that his shots will "be guided by the hand of Stalin himself", laughing every time he clicks his left mouse button. By doing this, he doesn't perform very well.
But let's say Bob witnesses all of these happening. Supporting the team, he saw his artillery hitting buildings, his light tank suicide scouting and flanking, and his heavy tank missing his shots. When he says his overused statement, he insults, if not most, but all 14 members on his team. It's just wrong! But then, the question is:
What should Bob do?
Blame his team for his incompetence, demotivating them every time he says they are shitty players, and leaving a mark of bad motivation AND bad gameplay, effectively making them having a bigger chance to do worse on the next match, or
Teach them what is right, trying to tell them the difference between mud and chocolate milk, giving some small but quality advice, and making them better players with the tiny baby steps that they need?
See? We can make the community better and better, little by little! It's such a simple thing WE ALL can do.
But before we make rushed conclusions/responses/comments, let's go back to Bob, and what he can do to do his part in helping the community.
Bob can tell Dan (M41) better artillery positions, and to aim his shots well, and to try his best to aim them at the tallest spot of the tanks - their turrets or their superstructures. He should also tell him that the best targets to aim at aren't the ones that give the most damage rolls; light tanks shouldn't be aimed at, even if they guarantee oneshots or severe damage. Bob can tell Dan to aim at slow, sluggish, and big heavy tanks.
Bob can tell Ryan (M5 Stuart) on how to scout effectively: passive scouting - good bushes to get quality spots off, active scouting - evasive maneuvers, good points/ridge lines to peekaboo/crest, and the tanks that are good to outmaneuver and the tanks that that shouldn't be attempted to try doing to.
Bob can simply tell Kevin (KV-2) to aim his shots, sidescrape, and to fall back behind a good amount of teammates to derp effectively.
But yes, Bob will have problems. They may not listen to his PM's, or they may just never be able to check them out by some odd chance. But there's a chance at least one of them will. One day, they will realize what they're doing is wrong, but we have the right to tell them before that "one day" comes.
If you just want to vent your anger to prevent yourself from blowing up, then don't say noob team!
Then just say "You guys didn't play well. Try harder next time."
With the above, there's a chance they will wonder why they didn't play well, and there's a chance they'll ask you for advice.
The world's language doesn't revolve around insults. There's always a better way to say things, and there's always a kinder option rather than the insulting option that so much of us choose to say.
Besides, it's not always your team to blame. It can also be the enemy's good play, some of your misplays, etc. If you can change your perspective to this, you can learn more and you can, at the same time, be less insulting to your team.
Wait, but yes, you can go rightfully insult. It is possible, and it is justice.
If the noob is a tier 10 with thousands upon thousands of battles, then yes, go ahead. Retards like that stay like retards and should be treated as retards.
If Bob still thinks this world has no hope for him - helping at least one player is too complicated, or that he's too lazy, the least he could do is shut his mouth. As my mother always told me:
"If there's nothing good to say, don't say it. Keep quiet."
It's simple. If you can't do what a good Bob can do, then at least do what a Bob with a mouth shut can do.
Note: I'm just posting this for the community to be less harsh. People at tier 1~7 or don't have thousands of battles yet still deserve hope, and they should be respected. But if they don't like your respect or don't really improve over thousands of battles, then go ahead make your freedom of speech go blazing away.
All I want to say is that some people deserve the respect you guys are capable of doing. Not everyone is a complete retard.
Thank you for reading, and I hope you guys will learn from it.
