Hmm...I see. I actually started playing it since the original WC3 Dota2 about 10 years ago. Back then i would buy only dps items and recipes.
then i read guides on playdota.com. Heck i even got my aunt to print them from her office printers. xD i literally byhearted hundreds of pages and pages of guides and followed the exact builds in nearly all the matches. Slowly but steadily i learned to get different items and what items are good for what situations etc. I also noticed that many new players dont understand what a "Unique Attack Modifier" is. For eg. Items like Eye of Skadi and Desolator don't stack. Mjolnir is also a UAM but stacks with some other UAM.
As for the "skilled players" try local 5v5 on LAN or request for 5v5 on an indian channel in-game. You can also join party stacks but they may be too good for you.
I can't "coach" atm. Currently hospitalized (and boy its so boring) because of a road accident the other night. Might stay a few weeks so dota2 for me.
ps: had to smuggle this phone in.
