how can i increase my mmr after these......?

There are many things i left out as i cannot transition my thoughts to paper which is a skill i should develop. Yes you have those games where you do get carried by your team, but you did play a role during some odd part of the game. I recently played a game this morning where i constantly ganked middle and my safe lane to the point where we were 8 kills to 1 kill by 10 minute mark. As you know crystal maiden has a tiny str growth, so that made me stick out like a sore thumb and red lighted me to die by their carry or nuker almost instantly. During my rotations to gank later on in the game i started to get caught and as i started to battle with my team i would drop instantly since i sat with little to no gold since i was the primary individual buying majority of all the observers, sentries and smoke to gank. Pretty much i created space early game and later on fed a lot.

There are games where you feed but your contribution towards the team may have helped whether you believe it or not. Your team was able to carry you because the opposing team knew you were a threat and had to get rid of you once they had the window of opportunity, by doing this your carry was able to steam roll them as they focused you down almost every single time.

I believe i give it enough credit but i do have individuals say i give it too much credit which i believe i do even though i dont state all my points.

I believe there are quite a few of you who need to READ this again.

I don't know if you're including me in those quite a few, since I'm critical of the mmr system. Especially the way it was implemented. But I'd say that as you've moved a total of 400 since it started that only supports my assertion that ranked matchmaking is only just starting to level out.
If you'd started at 2200 there's a very good chance that you would only be at 2600.

But im not a 2200 nor a 2600.

I know your not. But you easily could have been due to the arbitrary nature with which people's initial mmr's were assigned.

I'm pretty sure the system used your normal match making rating to pin point where you belong...

I think the MMR is nice indicator in which area your skill is, but definetly not an exact represntator for your level of play.
Of course you loose games because of team mates, but you also loose some, cause you didn't perform so well, or the enemy team just played better.

you can gain and loose rating so fast, that 200-300 rating don't really make any difference at all. It can just come down to pure luck, that you go on a loosing streak (or ofc winning streak)

Overall, you should play for fun anyway and don't give a rat's *** about rating.

Sounds like you're implying normal games. I play DotA 2 for competition, the thrill of winning or losing a good game. Also 200-300 points is alot, i'd like to see you move 200-300 points from your current location and there is a difference in skill level as you slowly move up. I've been +400/-400 from my starting rating and noticed a dramatic difference in individuals i play with. So from your experience and my experience are quite different.
