Rank and items

Hey guys I'm just here to express my opinion on the ranking system. Just a little background I've been playing Dota 2 and Heroes of Newerth for quite awhile in dota 2 I am at 5k mmr and in HoN I'm at 1953 after reaching the above average MMR I got bored of the game and then I started playing League. Do not get me wrong i think League of legends is a good game but I think it needs more improvement if you ask me especially when it comes to the ranking system and in-game items. So I started playing this game, borrowed my brothers account it was at lvl 26 and I played it until I reached 30 then started playing the 10 provisional games to determine the rank so I ended up being a Silver 2 (I only played 5 games by the way. the other 5 was played by my brother) I, personally, think that the "ELO" system doesn't work out well in this game. Don't get me wrong but this ELO system will make more players quit the game. I have an idea on how it works but what I dont like about it is even as a silver/bronze you already get to go against Golds/PLats. I know that its the balance bla bla bla but this is an RTS game the levels of the team should match the level of the other team so i.e if I am silver, let me match with silvers only and golds unless of course I am in a party with a few bronze. how can you make these players stay longer in playing the game if you match them with higher ranks and they get destroyed? theyll most likely quit the game. Another one is the item balance and role. I mainly play the carry role and compared to carrying in HoN and dota the carrying here is a fail. I average about 6:2 K:D as an ADC and as much as I want to turn the game around and do my job as a carry I can't, why? because theres just no item that can counter a fed AP champ or a tank unlike in dota2/HoN theres this item that's called Black King Bar (BKB) / Shrunken Head Which gives you magic immunity for like 10 seconds. There'll be more thrill in the game if you have this kind of item you dont have to have the exact effect but at least make an item that can turn things around. High Def heroes cant be beaten too early in game once they are fed because there is no such weapon that can reduce the enemy champions armor unlike in dota 2 / HoN they have a shield breaker/ desolator that can give you hope even if youre way behind. Im not looking for a loss of gold when you die I just want to play the real CARRY game. If you're winning and you have the most kills that doesnt mean youre a carry, carry is when your team is already losing and you're the only hope to bring them back in the game. maybe in lower ranks you can turn things around mainly because you're matched up with people who doesn't have enough knowledge of the game yet but in higher ranks it would be possible but the system doesnt give you that opportunity to turn things around. Anyways I just wished theres more balance in this, I know the LoL committee is trying to be unique about this but also wouldnt you want more profit from it? more people playing? I've seen a lot of kids quit already because of this kind of issue and I know people who are really mad about this and wished it would be more balanced.

Just a concerned player. thank you
