Infinite scaling

Am i the only one who find infinite scaling to be seriously a bad mechanic? For exemple Nasus or Veigar. Both lose lane hard and are really behind. They farm up their stacks... Boom, unkilleable machine who deal so much damage(Nasus), or burst you on each of their spell(Veigar). Thresh on other hand is a bit tricky, as even if he get stacks for his souls, it take a while to take any effect to actually impact the game, wich seems fair . Bard in strong when he collect chimes so he have to leave lane to get some and grow bigger. That's odd but fair. Sion get health for every minions/champions he kill. He also have one of the lowest base HP in the game so it's fair and it doesn't increase his damage to hard.. But honestly Nasus and Veigar are two champions that work all arround their infinite scaling and i feel it's a pretty bad mechanics. It shouldn't determine if the game is a win or lost because said champion farmed their stack, regardless of the team they were against.... You can downvote but please comment your reasoning behind it. Thanks for reading, have a great evening.
