Well I feel like riot changed the game specifically for flashy plays and highlights, so those videos and 'pro play montages' or 'ONE SHOT insert champ here
IS 100% BROKEN" yt videos are pretty much what they are aiming for. It brings people in and has quick gratification for the player when they can stomp the enemy team regardless of skill level. All of my games have been either stomp or get stomped. Sometimes the stompee loses though because they spend time trolling and stuff instead of ending the game efficiently.
Idk.... was talking to my friend about this yesterday. The game doesn't feel as rewarding as it used to towards skill and more-so towards building these insane AD items so you can plow through the entire enemy team. Some people complain about AP being busted but at least they have a mana pool to manage and are generally squishy and immobile. Zoe is pretty annoying with her constant summs/free item effects and huge damage + cc. Most of the AP items are expensive and they have cooldowns to deal damage instead of firing off a bajillion auto attacks a second.
Plus some champs hurt like a bitch but are also extremely mobile/slippery (kayn, yi, yasuo, etc). Assassins like Pyke get easy pentas by cleaning up after a teamfight whether they were losing or not. Stuff like that ruins the game for me. I can't reliably counter these things since zhonyas cooldown is so long. No amount of running will keep a wall ghosting kayn off of me. :\
Turret plating gold, bounties, scuttle, rift herald... all these things result in the winning team snowballing even faster than before. It's no mistake that things are this way. I guess riot doesn't think that players have the attention span to play games without all of the handholding.
