If I have an Ezreal on my team, what supports to take? List as many supports that works well with adc as you possibly know. I know there is a website, but that is outdated, plus a picture of picking support guide is pretty outdated as well. It's kind of like this: Jinx works well with Blitzcrank (at least I think I know.)
BLACK REALM GOD1 votesPicking a support is trial and error. There is no definite answer. Different players require different things. Just ask whoever is playing ezreal. He should know what he needs. If you're ever EVER ev-er in doubt that's what soraka is for.
Shukuchi1 votesI am just looking for what support is good with (adc), like what support is good for immobile adc, who is good for sustainable adc, who is good for a mobile adc, etc.
BLACK REALM GOD1 votesSquishies need buffers and healers
longshots need buffers and pokers
dashers need immobilizers and healers.
gunners need pulls buffers and healers.
what am I talking about? Who knows. Try to figure it out and you'll have learned a lot about support/marksman compatibility.
hp-defense-movement-range-damage-attack speed-resource requirements. If you keep a happy medium you will never win or lose. You must guard when struck and strike when the opponent is open. That is the only way to victory.
Aeolian Melodies1 votesPoke supports with poke ADCs, engage supports with burst ADCs, peel/sustain supports with late game ADC who may have a weaker laning phase.
OFC, this is a rule of thumb. Ultimately, you're better off playing a support that you can play well but has less synergy, and your ADC is not the only thing that factors in, because there are 3 other people that your pick needs to work with.
Ezreal really likes high poke supports, such as 
and especially 
.
Immobile ADCs such as Ashe and Jhin like supports who can peel for them 
and "I won't peel but you won't die either" aka 
, as getting caught is their biggest weakness.
Burst ADCs like Corki or Graves like supports who can lock people down, such as 
.
You can either choose your support for the inherent synergy, increasing what the ADC does best, such as MF+Sona lane (great poke, great bullying, great trading, very strong ult synergy), or choose your support to make up for the marksman's most blatant weakness, such as the classic Ashe+Janna (amazing peel for immobile, squishy Ashe).
