This guide on Diana shows her being played as a Jungle. She has really good AP Ratios and she has a good clear time and great late game potential. She's a lot of fun and a great champion released by Riot.
This Build Guide for Zed is to be played in Mid Lane and is written by Crs Extinkt who is a Platinum ELO Player who plays/played for Curse. Zed is a great burst assassin who is really fun to play, but has a very high skill cap.
This build guide for Diana is for mid lane and is by Chu8, a high Elo player and streamer on League of Legends. Diana is a strong early game champion with great burst damage and mobility while offering a small amount of CC. She is played kind of like a Kassadin, a bursty AP Champion that does massive damage, but is also a melee champion and will only do well in certain match-ups in mid lane.
