A lot of people use DFT on Lissandra
Why? I mean, I wouldn't call myself a pro Liss, but I do main her and I use TLD because over all it really adds to her damage given how spammy she can be. I just don't see how DFT is anywhere near TLD's level because her spells are AoE, so they only apply half the damage. Plus to get DFT, you give up Intelligence in the Cunning tree which is really great on Liss to be honest, because her Ult is up every 44 Seconds and you can spam E quite liberally to get around.
