I recently started playing supports for basically the first time in like half a year so I have no idea what to do. Even though they are for some reason incredibly fun, I have no idea what to build.
Please give me ideal builds for: -Zilean -Karma -Soraka -Braum -Ali -BC -Sona -Nami
Please also tell me WHY this is ideal build and not just post it. Thanks.
ok what im gonna do is split your support list into three main categories based on what gold gen item i think should be used on them
ok so first we will start with:
Start: 
{
then early game you would normally buy: 
mid game-ish: 
either 
or 
and honestly a 
is a good pickup
and late game: you finish off the build with a couple of tank items of your choice, so the thing here is with this build on both alistar and braum you provide good vision control along with very good tankiness and enagage this also applies for blitz but blitz can honestly use either the relic shield tree of gold gen items or the ancient coin tree well so i will also provide a coin build
Second group will be: 
(sona also works with the spellthiefs tree of gold gen items but i personally prefer coin)
Start: 
early game: 
(pretty standard on every support early get t2 gold gen sightstone sweeper and boots along with occasional pink wards and switch to sweeper trinket)
mid game: 
either 
or 
or even 
can be good choice here if you want but thats depending on enemy comp
is also an ok choice here because both sona and zil like mana regen and cdr and those are never bad stats on most non tank supports
later on: you can finish this build off with more utility items more ap or even a tank item or two depending on what your team needs this build should give you good utility and engage/disengage on these supports
Last Group:
(im actually not that good at these supports specifically so this might not eb the most accurate build set)
Start: 
(its a pretty standard start on supports you can however skip the green ward for more potions if needed on any of these builds)
early game: 
mid game: 
or 
is an option here because these will be more poke focused except for nami who it still works reasonably well on you can also go for more mana regen or 
if you want more tankiness the slows and the ap
Late game: you can finish off with either more utility or more ap depending on the circumstances
ok since these are more poke focused supports most of the time you want your poke to damage so with this build you can do that
ok hope this helps as a sidenote upgrading sightstone to ruby sightstone is a good idea at around 25-30 minutes if needed i personally play alot of tanky supports so sorry if the builds for the other two categories arent amazing but they are usually what i go with on those supports so i will say something else about these supports alistar and blitz as supports focus on getting kills in lane usually for their adc braum can also do this but he is a bit better at defending his adc soraka isnt very likely to help win lane but she is going to make sure you dont lose lane zilean is more focused on getting his adc out of bad situations and name is focused on well healing poking and cc so you can kinda do a lot with her, as for sona and karma they want to poke and zone the enemy bot lane away from farm and if they can, net their adcs some kills. hope this helps you!

Always 
, boots depend on the jg AD is AP is always with Homeguard.
After that it depends on the other teams make up. Generally pick 2 of the following, 
People will tell you to use instead of but I personally find the to have more effective tools for my style of game play.

Always and 
with Homeguard. Then two of the following 
and 
for only. I try to maximize CDs and Mana Regen and movement.
Vision is priority for support so your first 800 should be to get a .
Beyond that it is going to change a lot depending on your support pick. I main Soraka and Sona so I'll give my take on them.
For Sona 
start
then or 
next. You can buy the other one after. Then it is pretty flexible for last item. Don't forget to switch trinket for sweeper after you get SS. Do not upgrade it is worthless to upgrade. instead swap it out if you find the game goes that long.
This build is to really suppliment her ability to add damage to her team. She becomes a damage support as she provides lots of extra damage to your team with the 50% crit to +20%ap and the +15% as and lots of extra magic damage on hit with censor and her Q.
For Soraka start if enemy duo is not a bully lane as you have so much sustain you will likely get a chance to place the pink and control a section of the bot lane. Otherwise start 2 and .
Build order: then 
or depnding if we need more peel/chase or lane pushing. Then I purchase the other item. I sometimes build 
but only if we get a good lead in bot and the enemy team doesn't have the best tools to get to me when i am healing.
This build piroitized CDR to help soraka get to 40% cdr quickly so her healing hits it's power spikes quickly. getting a huge heal on a 1.6 second cd is crazy powerful. Talisman is her means of escape and she heals so often it is easy to proc Zeke frequently with her. Twin is great for helping her scope her area when warding so she doesn't get caught out and helps give some peel and makes it easier to land E root.
That's a serious variations of support you mention their. With a lot of them it really depends on what runes you have setup for them. First let's devide them in a fell groups:
#Tips
pre 10 minutes before all 3 inner turrets are down
, vs heavy AD , vs a lot of crit 
, etc...)http://champion.gg/statistics/#?sortBy=general.winPercent&order=descend&roleSort=Support
