How not to be bad vs Ziggs Bot

Don't stand near minions (he has a larger explosion radius on minions) and try to trade when he misses Q.

Have intelligent runes. Use scaling health and flat MR not AS glyphs or armor seals.

Itemize intelligently. Get lifesteal and MR (Hexdrinker) to negate his poke/burst.

Get manaless waveclear with Shiv, Runaan's etc.. and shove him in forcing him to burn much more mana than you when clearing.

He's pretty easy to beat once you understand these basic things. I feel like people play SO incredibly badly vs him that I had to at least give some tips.
