I never once said i was going to stomp golds, i made a smurf account so i don't destroy my mains mmr in pre season. All the players i vs should also be smurfs, so i'm not even vsing golds so that destroys your theory. My game's in promo's where me facing P5-P1 so i rarely even saw a real gold player.
We are going off op.gg now? I can't even remember the last time i saw cassiopeia in a league game also she's a mid laner and i'm a top main, Nid is a jungler she has to hit her q or trap to get the bonus damage, i don't see her picked over kha'ziks who has op q which you can't miss a free dash a slow and can go invis (A lot easier then relying on skill shot) lee ( Has an excellent engage with either his q or w and high damage if he misses his q and still dash and E's you for the slow with a ult to execute you or knock you back into a Allie champ then disengage either by q or w) Eve (can be preeminently invis after level 6 she has a stun and super high damage near impossible to track her on the map and once she gets going you're not going to live once the charm is hit, lets not mention the movement speed buff and execute R which also gives her an escape)
(Also win rate doesn't mean a champ is broken) Wait so Urgot beats Panth very easy in lane, same with Aatrox, now panth needs to win lane in order be useful and have an impact on the game or else he's useless since his kit is one champ combo.
Now let's move out the laning phase, panth finds it hard to engage since's he doesn't have disengage you either all in get a kill or you die. Now urgot has excellent kit for engages he also has sustain and execute and can rush Black clever gaining hp and damage, Aatrox is the same, has no manna costs and excellent engage kit with little to no risk with an ult that allows to out damage you for the 10 seconds.
All the champs i gave examples off have excellent game play all match long, and don't fall of into the late game.
