Sure these have already been asked before but oh well.
Will magic pen numbers be changed since we are losing a lot of Pen ad and ap
Does DOT abilities work with scorch? Zyra plants/Malz ect.
When the description says "unique attacks" does that include damage done by one of your minions like tibbers or Kat's passive?
Thanks

Probably not, as mr/Ar are being reduced(because you can't gain +12/+9 of them) and some runes give mpen and lethality. No more 50 mpen Zyra games, doing true damage to all without significant mr items :(

Zyra plants are aoe, not dot. Once a dot is applied it does damage over a duration and cannot be dodged(barring invulnerability like Stasis or Kayle ult), aoe is multi hit, and can be dodged.
Malz will still hurt you with his e if a Tahm hits you, Zyra will not.
That said, maybe? There are not any dots that apply for 20 seconds, so you can't get 2 procs in one, but you should get off one of them.

Pets yes, but only once(not sure about multiple pets, like two Zyra plants or Malz voidlings), Kat's passive is the aoe damage correct? That might apply, though aoe damage passives are kind of buggy when it comes to items and systems(Galio's and Diana's do not proc the dot damage/healing from 
for instance)
