Advise for new player and Riot

To all new player who is sucking at the game right now. The reason you are sucking at the game even though you have a good ping is because you don't have the skill and another reason you go with the recommend item riot advise you. The first reason is pretty much obviously but why you go with the second reason is because you follow the recommend items that riot advise you? Because they don't play their own game and so their recommend item is wrong...Well, not a hundred percent but it gives you a really good disadvantage enough for you to be the burden for your team to carry. For example: Today, I play Yasuo in the mid lane. For the start, I buy Doran Sword to play against the other Yasuo. Well bad day for being Yasuo, The other smart enough not to follow the recommend item so he buys Doran Shield. And So for the rest of the game, I always lost to that Yasuo in a solo match just because the stat of the Doran Shield make my Doran Sword become the paper sword!!!. In general, I can beat any player on his team in a one vs one except him just because I still have my Doran sword and he still has his Doran shield. I have 5 items the same as him but base on the stat I only have 4 items and he has 5 items. Go harm with a defensive item right at the start, nice logic Riot. --> I wonder if I'm a retard or Riot is? Because I consider myself as a returning player they have changed so much since I left. So I just follow what the game advise to buy (Probably the biggest mistake) and I realized I had been doing it all wrong by following the recommended items rather than spending 15 minutes to decide which items should I use in the all items section (I really can't find the button to set up my build like before) and how much retard Riot is right now by changing the stat but don't recommend correct items in order to have a good advantage for new player and returning player.
*I know Riot is trying to make the game much better and balance. Well here is my comment: the more balance you try to make, the more unbalanced it is --> There is no balance so stop looking for it. This is a huge mistake for the game developer nowaday alway try to find the balance. If there is a balance there won't be a genius and a retard in this world. The game right now is nowhere better than in the past except for the map and appearance of the champion. To Be Honest, I played league of legend since the Baron look like a purple dildo and the dragon look like a bull with the bat wings but in the ASIA server. Then I leave for a really long time until they rework the map. In my memory, I have no record of the Doran shield ever able to block all of the damage of the Doran Sword. Even in a logical way, you must think shield can block the sword. Yes but no shield can block a sword forever!!! The shield will break if the sword hit on a spot over and over. So there you go the answer for the legendary question why you suck at this game is not because of your skill alone but YOU HAVE TO PUT YOUR PRECIOUS TIME TO RESEARCH HOW YOU SUPPOSE TO BUILD ITEMS, RUNES. MASTERIES FOR A SPECIFIC CHAMPION. Can't do that then stop playing this game you are just wasting your precious time and others.
