2 weeks in, requesting any advice

i dont agree with this. a supports job in the early game is far more difficult and crucial than that of lets say a hardcarry.

where a hardcarry "only" needs to farm and not get killed the jobs of a support cover a wider area:
placing wards and buying courier for example already mean, that the support player has less startitems and is more vulnerable at the beginning of the game.

Secondly supports should harass the lane and try to let the carry farm, which does 2 things
a. they arent getting any items soon and therefor fall even more behind in statgain (and therefor survivability)
b. since they should be the main aggressors on the lane, the chance, that they get initiated on is rather high --> a good support player has to see, when to be aggressive and when its better to retreat, else wise they will just feed.

playing a good support is harder than playing the carry in the early stages of the game since a supportplayer needs high mechanical knowledge (both of his lanemate and the opposing laners) and good decisionmaking.

Its true that the need for supports fall off later in the game, but a support that gives the enemy carry 3 freekills in the first 15 mins of the game, may already have lost u the game.

But the point is, if you, as a carry, don't do well at the start (as an inexperienced player might), you will be useless later in the game, while a support is useful for the most part of the game regardless of level or having a bit of a hard time.

Being a Hard Carry isn't all that easy. You need to last-hit well, farm, know where to farm safely, know when to enter a fight and when not to, have map awareness to prevent being ganked, especially in jungle (because your supports might be busy in teamfights elsewhere and unable to check the entire map 100% of the time, especially in pubs), etc.

...Also reading ****loads of guides in free time, even these for begginers and heroes i don't play.

well...if u switch the "farming" part with ganking and warding, its pretty similar to a supportsjob. providing map awareness, knowing when to be were. Making decisions if its safe to initiate or when its better to retreat..etc. I dont say, that the hardcarries job isnt hard or important....im just saying that a (especially new) player may struggle more with correctly playing a support role than a carry role ---> though neither is advisable for new players imo.

Guys you are talking about each role, but you forgot that we are also talking about low lvl pubs, where carries carry because they got lucky kills not farm, where supports rush aghs and stack mekansm, where initiators don't initiate and semi carries farm in jungle. Let new players play what they want to play and learn how to do some things. He won't play with perfect carries or supports, so why not give him a chance? If he fail he will know what to do better next time, rly =.=

Also i agree with the statements, that playing vs bots wont help u learn the game as fast, as if u were playing vs real players. Bots usually do the same every game ....(on medium level) they dont harass, dont deny and lasthit rather poorly. Furthermore, when the first tower falls, they start roaming as 5 and instantly tp (as 5) to a tower that is threatened by a single player.

cant recall if this has been mentioned yet, but also try to look for some pro streamers, that play heroes that u are familiar with. Often u can already profit form watching some1 doing a spell-chain correctly, or how and when he uses his spells.... at least this helped me alot when i was new. Best would be a stream with commentating, so u know what is going on and why.
Tobiwans stream on twitch.tv comes into mind.
