Dft or tld on syndra?

She is a burst made with AoE abilities so tld all the way.

Agreeing with Frosted Prince, normally a burst mage would take TLD.

TLD if you want to snowball and feel comfortable doing so vs your laner.

DFT if you feel practiced enough with syndra and moreso want extra boost for teamfights and late game.

She applies both easily and can mantain both easily. TLD is far better unless you're facing someone who you really doubt you'll be killing or be able to roam against.

I usually take TLD on her.
