TF build now with the new AP items?

Hey guys! I'm a TF main, been playing him since season 2, I have probably 400 games logged as him in normals and ranked combined. I'd like to discuss his build and build order now that most of the AP items had an overhaul. To start, I usually build: I run Ghost/Flash with the distortion boots to lower my ghost CD and get that flash speed boost. Now, sometimes I swap for or for the extra CDR/mana regen or if I'm going against an ap assasin, such as LB or Fizz. Now, if I run morellos or athenes, I usually run Sorc boots instead of Lucidity. Now to the actual part of the discussion. Now, is it worth it to swap out a couple of items for the new or ? I lean towards no, but I want input on why or why not. I could see being really good for wild card poke. Giving that extra aoe slow utility is nice, but tf has a built in aoe slow in the form of the red card, the only difference is that it's 525 range, whereas wildcards is (900?) range. Any input would be nice, I'd like to hear people that have tried new builds and stuff too
