Riot Stop taking away items

I feel so limited when it comes to the variety of items in this game. I love the game ive been playing for years, Since season 2 to be exact. But its getting to the point where im buying the same items every game with very little diversity. Instead of making old items build into something new that already existed, Why not just bring back old items and create new ones. Bring more item choices into the game for each role. Even if some items were broken in the past bring them back, change em up. You've changed warmogs about 3 or 4 times now. When i first came i remember it use to stack, then you changed it to a flat hp item, then you reduced the amount of hp it gives but gives it a like passive. I mean why cant we do this with force of nature? Why cant we do this with heart of gold, fairy charm, executions blade, etc. Bring back some of the dead please and give birth to alot more
