Dear Riot: Please give Syndra...something
Lower mana costs. A little more damage. Better Transcendent bonuses. Something...
Honestly, I wouldn't expect Syndra to perform well in the current meta since 1. the reduced Q damage (since 5.1) makes her much less of an early lane bully, and 2. Syndra's strengths are high single-target burst and the potential for strong multi-target CC, but the former is less valuable in a tanky meta and the latter is more unreliable since the moderate E nerfs (huge nerfs in 5.1 but since scaled back). But, I think it's pretty clear that there's no compelling reason ever to pick Syndra as things currently stand. Which is sad...because I think she's a really cool champion.
I don't want to recommend anything specific since I trust Riot to do a better job than I could do just theorycrafting. I know I'm not the only one who's made a post like this. Just wanted to contribute to the steady stream of "please buff Syndra."
