This guide helped me start playing Zyra correctly. I was always terrible at using Zyra for support, but with this guide, she is in my top tier supports :D. I've brought my team back into games with baron steals with my ult. Zyra is way too fun to play! Great guide man, you did a great job!

There are enough guides out here that are both BBCoded and educational at the same time :P. Guides will mostly be judged on both content and BBCode, it's not that everyone will be voting on guides just because the BBCoding is insane, but they're definitely also judging on content.

Moving on to the guide: I don't like the rune choices. Greater Quintessence of Gold are as good as completely off with the current gold masteries/gold items, and for glyphs I'd rather go Greater Glyph of Magic Resist because supports deal more damage nowadays.
Other than that... the guide is decent, but rather short. Matchup section could be added, for example, and maybe some gameplay. You did good for a first guide, though.

lolwut...you want to strain your eyes and read walls of text? BB code is a courtesy to the reader to make it easier and more enjoyable to read...

Pretty good guide. Glad to see a guide with no BBCode. I'm fed up of BBCode, this is an educational guide and not for entertainment purposes. Good work friend.

Oh this is actually a really helpful guide thanks :D

Not bad ... But try some BBCode. Check this ! => Making a guide
