Too weak/not as much fun anymore

I used to like playing these where my top favorite champs to play but recently there been soo many changes to these champs lately it's not as much fun anymore. For Example, syndra I used to dominate lane but now it seems almost any and every champ does more damage than her maybe it's cuz I don't build or play her right but I have tried multiple ways of playing her build her but still no where near strong enough as she was or at least gives her most potential. to put it simple and plan you guys NERF these champs way too hard making game play so unbalanced.
