Oh the insight of the community... Since when do you build BFT for mp/5 or 20% CDR? All these added stats and costs to BFT are nerfs to the item. Can u guys even remember what BFT was supposed to address?
I'll give u a guess. It wasn't for CDR.
BFT was supposed to address the trouble AP casters were having with bruisers that forced you to build glass to put enough dmg on them or meet their innate tanky-ness forcing you to put out much less damage in comparison to bruisers in the early/mid game where AP is supposed to be at their strongest . Initially, BFT did that wonderfully. But because the way the item worked with DoT spells, it pushed the strength of certain champs like Teemo.
So the result is a set of heavy nerfs to BFT that has made the item unfavorable for the role it was supposed to accomplish (which is to counter the beefy bruisers). The 4k investment hurts as we consider APs building the item during the early game / mid game. And as it currently goes, there is much better itemization alternatives. If I wanted mp/5, there is AA and AUG. If I wanted CD then Sweeper/Ionia/Masteries/Runes. If I wanted AP then DFG and Woogets.
As it stands, BFT tries to do too much for what the item is supposed to do.

I still get it on Syndra (poke+damage+CDR), but on Orianna I'm not going to go for it (she's a support mage with so many more cost-effective options.)
Incidentally, I find it is more valuable on light support-oriented AP due to the stats, whereas stronger AP benefits from getting faster AP in DFG/Woogets/Sweeper/Blasting Wand build paths.
