Newer player Looking To Improve

Hello there everybody! How's it going? The title pretty much explains it all! I've been playing daily for about two months now. (Not a ton lately due to increasingly frustrating computer problems) I'm truthfully just trying to find new ways to improve. 3K MMR is pretty easy for me to play in. My lack of climbing is due to my lack of playing ranked.

As an Ex-LoL player I have a firm grasp on basic to intermediate mechanics of the game. I have relatively solid game knowledge and a solid hero pool that I can play comfortably. I am comfortable with all roles, however; my main roles are solo offlane and safelane carry. I also really enjoy playing support.

Any kind of tips you can give me will be appreciated greatly.

Here is a link to my DotaBuff. Feel free to be blinded by my garbage play in my last few games :)

Edit: Just for anyone curious, my highest rank in LoL was Platinum 1 with Mid-High LP

Hey! I'm far from being the best, but I am sure I can give you tips, Im gonna add you, see you in game probably!

Watch videos, read guides, gain experience.

One of the main issues I see at 3.3k is the decision making. Players don't know when to back, or when to push, or when they can get a quick Roshan kill in.

Look at your minimap every few seconds just to ensure you're safe when pushing, and always carry a TP.

Watch videos, read guides, gain experience. Only way to really improve past basic knowledge. Nobody starts amazing at this game.
