I always end up tellign the other players "relax, it's just a game". A lot of players want to prove themself and others something. In Dota is MMR which shows your "player value". Actually it shows the value of how good you play and where you belong as a player. But since Valve decided to show it openly, players think this is a leaderboard like in many other games. The value determined in what region of players you belong (after all, it's called matchmaking rating) and if you have found your perfect rating, you won't go very far up or if you go up you will find stronger players that stomp you back to where you belong. Some acknowledge this, most other players however think that there has to be a steady uprise on your value since you "are better than all your teammates". This results very often in cursing other players even if you have only around 50 points more (~2 games).
Like I said before, there is a big misunderstandin of what MMR actually is. People think it's a leaderboard and like in any leaderboard you can improve yourself. This is true and false at the same time. They are blinded by the performance of professional players that play in the higher ranks. However, these players play and train an entire year with the same team and therefor have a better understanding of the game. A normal player plays around 5 games per day or less. And of course not every day. And to be honest, there is a limit on what you can do and learn in Dota and if there is a player that is better in it you will never beat him. "Skill" like most casual players want to explain, plays actually a very little role in the game. Luck plays a bigger role than most people think. Last hitting is, to an amount, a luck based system. Of course you can try to train the rythm to get a better result on getting gold but in the end it comes down to luck: Are you fast enough before a creep or another hero beats you to it? Beacuse everyone wants this last hit, you, your fellow tem mates, even the enemy team wants it. And all these factiors play allong at the same time. You can train yourself to a better understanding how much HP the enemy must have left for a last hit. That's all. Bit you cannot speed up your hero or stop others from doing the same thing.
Then there are kill steals. Players like to shout at others that "steal" their rightful kills. In my opinion in a team game there cannot be a "stolen kill". It's unimportant who get's the kill, it's important THAT the team get's a kill since that's what you want, the enemy team dead so you have some time to push.
But people really want to show of how many people they killed and they have more gold in their pockets than they can spend. Still they deny that you deserve also a kill just because they did the main portion of the fight. Some roles will end up with really low money in the end game and will struggle to survive but the carries, that don't need any money anymore, still deny them the gold because they think they are not worthy of it. In the endgame the support is mostlly picked a starget of the enemy team because he is the easiest target or even the only target they can kill. And than your team cries "What a lousy support, dies all the time. Buy this, buy that". Yeah, with what money? And, to make it clear, the main portion of a kill goes anyway to the guy who dealt the most damage to a kill. The only thing that changes is if you get a digit in kill or assist and players think that kills are more important than assists (it's irrelevant in my opinion, I always count both together).
The new Dota Reborn player profile shows in my opinion a better understanding of player roles. It does not only shows your victories or how many kills you had, it shows if you did support, push, kills, are a flexible player (plays with more than one or two heroes) and shows perfectly what role you fil. In my profile for example it shows that I'm an very flexible play, playing with a lot of dofferent heroes and playing mostly support with less farm and kills. It gives a perfect example of what I am: Support, not carry.
I think this should show up at the beginning of the game for every player since it's important. Otherwise your team tries to fit you in a role that you cannot play.
Another thing I want to mention: The International is over, EG has won. And directly after they've won there pops up messages that EG has thrown out AUI_2000, the player that provided the victory.
The reasons are mentioned on different sites, mainly it seems that one of the members has to step down his role because he get's a hand surgery and cannot play as fast as before. AUI has to make free that spot because of that. Than they take in another (exmember) player in the team that takes the role o the carry. Some people think it's backstabbing, other think it's okay.
I'm not very sure what to think of it. I think it's a bit hard to throw out someone who had a big impact on obtaining the victory on the other side it's still a team game and the rest of the team did also their part. It's not like that AUI won't get his cut from the prize money anyway, he get'shis share and will move along, goung into another team and probably raging against his former team on the next international. Or not, we will see. For now we can probalby see some changes on how Dota will be played because int he aftermath of the TI everyone tries to do the stuff they've seen in the torunament. And I think that's actually the part that annoys me the most because those players think their strategy is the best but in the end they didn't even invent it nor do they really understand how it works. They just take it out of the context and don't try to adapt to the situation. Very toxic for the game.
