pro's
-Poppy support allows you to have a massive burst lane
-controls lane to allow adc to farm and minimize cs of opposition
-strong turret dive at lvl 6
-very good late game damage, and tank
-very easy to claim first blood in low elo's
-lots of lols

cons
-no heal
-if your not communicating, or working well with your adc fail waiting to happen
-poppy support is scary vs a soraka lane. if they poke you you have no sustain so you have to burst them down in one go

-KEEP LANE BUSH WARDED!!!!! cant stress it enough.
-use 'E' to smash them into wall of your warded bush, cant be done if its not warded!
-pink wards very strongly recommended or even oracles to control that bush full out
-if you control that bush you contorl the lane, you have them zoned so hard they cant farm, and if they try to farm jump them

don't farm, your a support.

Probably fairly common..............
but i get lipped for supporting poppy often, when reality is a good poppy support controls the lane.

doesn't matter what you take. Heal is nice, but not essential.

team work is essential for a bottom lane victory!

WHAT ARE YOU DOING IN THE JUNGLE?????? YOUR A SUPPORT!

I keep a slot open in my build for wards... you can if you want, or build a tri force, or some more tankyness, or some more awesome possum-ness.
