Alright, So. This guide is very general. It tells you what to build and why, However I think 3v3 teams would really benefit if you would expand on what to actually do in-game. I can't count on 2 hands how many people I've had on random teams (As our 3rd) that actually don't know what they are doing (at all) in support comp, I play at the Diamond level and usually they pick something stupid because of it then say they didn't know what to do. I myself even can't do it that well because I main Jungle and everytime we try to do it with a 3rd, It goes horribly wrong. Other great picks you might think of adding to this guide are Gragas and Maokai, They still build the same.

Cheers,
