The community is just getting worse and worse. One of the main reasons people transfer from LoL to DoTA is because LoL's community is terrible to be in and DoTA's is slowly getting just like it. Don't get me wrong, I still play LoL occasionaly for a fun and casual break from DoTA, but DoTA has more technic and struggle to be played *too* casual for my liking, so I play DoTA for fun, professional matches.
When I load into a match and chat is spammed with "Go support" "Omg y no carry?" "y u didnt support? ur noob" it urkes me as I'm sure it does many people and don't give the whole "What if the team has gone all carry" because granted a balanced team has a real good chance of winning, but so does an all carry team if they players know what they're doing. You get 10 minutes into the game and maybe you've had a bad start, you've died maybe twice and one of your 'team' mates types in all chat 'report "xxxx" pls" and that continues through the game? No, stop that, someone had a bad start and chances are, if they know what they're doing, they can make an easy comeback.
Second; "Mid or I feed" do you know how immature and sad that makes you look as a player? Really, grow up. That goes for the term 'noob' as well, what is this, 2009?
... Not to sound like a complete and utter cow bag, which I have (lol yey controdiction), don't get me wrong, some of the community is lovely. I found a group of people I instantly made a team with before because they played and co-operated so well. More like that.
