You're either bronze/silver or Challenger. Not getting pots is so incredibly stupid.
Say you don't get get pots, you now have extra 100g for an item later. If you make any sort of mistake and lose health, you play safer and miss cs and exp. You buy the pots and you get staying power in lane, meaning more cs and exp which will easily out weigh 100g from not buying early pots.
Yes its Cho, but you can easily get zoned and taking an enemy AA or ability will do way more than the health gained from killing a few minions. Early game Cho will not be staying at 100%hp like later where he can oneshot a wave and gain back tons of hp.
