User blog comment:DarknessStriker/Which support should I choose?/@comment-6906412-20130521071606

Right now Thresh is probably one of the two strongest supports next to Sona. Thresh plays a very aggressive lane, and is perfect with and ADC like Vayne or Draven. Nami is also very versatile, bringing lots of cc and healing to the table. Like Sona, Nami is flexible and works with most AD carries.

I personally am strongest at supporting with Lux, her amazing CC, scouting ability with E (Lucent Singularity), strong double shield, and kill potential with Final Spark (R) make her my favorite midlane and support champion. Lux pairs best with Ezreal and Varus, but works well with most AD carries. Zyra plays similarly to Lux but Zyra offers no defensive options (shield or heal). However, Zyra has one of the largest AoE CC ultimates in the game, if not the largest.

The decision is up to you. As a straight up support, Thresh or Sona are my favorites, with Janna and Nami close behind. If you want a multirole support, Nidalee and Lux double as strong mids (Zyra not so much after they nerfed her AP ratios, etc). Elise also performs well as a toplane, support, or jungler, but she has a more difficult and complex set of skills. Out of the supports I have played, I prefer Lux>Sona>Thresh>Leona/Janna>Nami>Nidalee>Soraka>Taric.

This is all my personal opinion, the decision is yours.
